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.

Sirgay: But I already cross checked. It gave me a balanced equation. |

generalbush:There was no 13 in the question, please check again. |
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by generalbush(m): 7:49pm On Nov 26, 2017 |
Sirgay: Mistake.I wanted to type "-3" I will edit the question. |
Re: Maths Guru Please Help Me Solve This Simultaneous Equations For My Young(photo) by Sirgay: 7:50pm On Nov 26, 2017 |
generalbush:Ok please carry on |

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 non-fractional 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:I know that must be an error, thanks for confirming it. |

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 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 |

generalbush:You are wrong the answer is Y = 4 X = 3 |
