For question 1

[s][/s]

X/1 - Y/2 = 1 -------------- eqn 1

Removing equations, we will multiply all sides by 2

2(x/1) - 2(y/2) = 2 * 1

This will give us...

2x - y = 2 ----- Eqn 1


Solving eqn 2...

x/2 + y/3 = 17/6

Multiplying both sides by 6, it gives us...

6 * x/2 + 6* y/3 = 6 * 17/6

==> 3x + 2y = 17 ---- Eqn 2

Combining both equations...

2x - y = 2

3x + 2y = 17

Using Elimination method, I multiply eqn 1 by 2 and eqn 1 by 1

It gives me ==> 2* 2x - 2*y = 2*2
1* 3x + 1* 2y = 1* 17


It gives us...

4x - 2y = 4

3x + 2y = 17

Subtracting eqn 2 from 1

It gives us...

7x = 22

x= 22/7

Substituting x = 22/7 in eqn 1, we have

2 (22/7) - y = 2

44/7 - y = 2

Multiply all sides by 7

7* 44/7 - 7*y = 7*2

==> 20 -7y = 14

- 7y = 14 - 44

-7y = -30

Divide both sides by -

y = 30/7

Check the solution again
17+4 is 21... Therefore x=7

for Number 5

Solution

F - 2g = -3
2f - 3g = 1-2

Using Elimination Method

Mutiply eqn 1 by 2 and eqn 2 by 1

=> F - 2g = -3 ----- x 2

2F - 3g = -1 ------ x 1

This will give us

2F - 4g = -6

2F - 3g = -1

Subtract eqn 2 from eqn 1

==> -g = - 5

divide both sides by -

==> g = 5

Substitute g = 5 in eqn 1

2F - 4 (5) = -6

2F - 20 = -6

2F = -6 + 20

2F = 14

F = 14/2

F = 7.



FOR QUESTION 4

Typing...

This is wrong. You supposed to equate both the first and second terms to 1. Like...

F - 2g +3= 1
2f - 3g +2= 1
Which will gives
F-2g=-2...........(1)
2f-3g=-1...........(2)
Multiplying (1) by 2 gives
2f-4g=-4.......(3)
2f-3g=-1.......(2)
Subtracting eqn (2) from the (3) gives
-g=-3
g=3
Substitute for g in equation 1
F-2g=-2
F-2(3)=-2
F-6=-2
F=-2+6
F=4

Seen mine...

talk2dre:
I have done that but its still the same issue.

I now tried to use the 'forgot password option' to start the whole process all over again.

After inputting the secret answer, it showed SUCCESSFUL.

I then tried to log-in with the default password which is the SURNAME, but it kept showing 'INCORRECT LOGIN CREDENTIALS'.

I used the old password, its still showing 'INCORRECT LOGIN CREDENTIALS'.

I'm at a loss at what to do now

write your surname(password) in upper case

DokitaDave:
Sorry about that.

A friend had a similar problem. He tried to reset his password, after which, he could login with his surname entered in uppercase.

If this isn't working for you, may need to keep trying to reach the school's help desk.

Thanks for sharing this. I've been unable to login since last week but I've been able to solve it with this

Hussmanov:
please l used a white background for the passport but the print out from d system is portraying it as a grey colour, l don't know why d background isn't perfectly white

How did you solve the logging-in problem
That's the problem am facing right now

chloe7:
it's most likely the Internet connection

I did the registration on my system but later went to cafe....... I even used my phone but the thing isn't going

augster:
Select the subject first, wait for it to load then select the grade

the subjects are not even displaying

augster:
Select the subject first, wait for it to load then select the grade

it is not loading.... I waited for like 30 min while doing it this morning

augster:
NO!

what should I do now because am totally confused

Good Morning guys......
I'm having issue with the uploading of result. It is not displaying subject to be selected for me. Am I save uploading the result only without selecting the five subject am using

Jodekss:
gooooodu. Be prayerful and work hard. Understand your system of studing or reading that pays well when you come around to this campus. You don't go and read cos you see people going to go and read, if it is burning the mid night candle that pays you well, continue and do it advancely. It is important to know yourself or system of doing it here. It is not all about studiiiiiiiiiing all day (here), information helps a lot. Mingle with productive heads. Not all wanna make it out strong, some just come around here to show swags though some show swags and still do fine why? Cos they know their systems wella. I have a studing mate but I read most of the time on my own. It helps too. You do and ask questions together and see to good answeres together. Attend all lectures if it is a must to you. Remember, God first, others follow.

Thnkz guy.... I'll take note of yhur advise
