for Number 5 Solution F  2g = 3 2f  3g = 12 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.

Sirgay: 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 2 Likes

generalbush please check how you got 60/6 (60 over 6) the improper fraction or something, isn't there an error? 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by dejt4u(m): 8:19pm On Nov 26, 2017 
Sirgay:change all the equation to nonfractional linear equation for question 1 and 2. for question 1, multiply eqn (i) by 2 and eqn (ii) by 6 for question 2, multiply eqn (i) by 2 and eqn (ii) by 6 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Sirgay: 8:20pm On Nov 26, 2017 
dejt4u:please help me with that. I can't am too old for maths lesson. 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Sirgay: 8:27pm On Nov 26, 2017 
generalbush will 2 whole number 5 0ver 6 gives us 60 over 6 in that question one solution? please check. 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by generalbush(m): 8:28pm On Nov 26, 2017 
Sirgay: Nop. 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Sirgay: 8:29pm On Nov 26, 2017

generalbush:Ok 
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Yemluvkid(m): 8:52pm On Nov 26, 2017 
generalbush: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 F2g=2...........(1) 2f3g=1...........(2) Multiplying (1) by 2 gives 2f4g=4.......(3) 2f3g=1.......(2) Subtracting eqn (2) from the (3) gives g=3 g=3 Substitute for g in equation 1 F2g=2 F2(3)=2 F6=2 F=2+6 F=4
