that was on my maths gcse paper today

x= 4
y= -2

x=4 y=-2

3x+2y=8 (times by 2)
2x+5y=-2 (times by 3)

6x+4y=16
6x+15y=-6
take away.
-11y=22
y=-2

2x+5y=-2 (substitute the y you've found into one of the previous equations)
2x + -10=-2
2x=8
x=4

You know there's no question right, therefore i made my own.

here is the answer.

3x+2y = 8
2x+5y = -2
x+8y = -12

Ah same I had it too I made the ys the same because in all of our practices we never had to put the x's the same I worked my way around it until I got 4 for x and some how -2 for y but crossed both answers out although the 4 is still in my working out.

Thanks guys

What did you get for the last question?

Im slow today.

3x+2y = 8
2x+5y = -2

x = 4
y = -2

3x is 34 or 3x4?
2y is 2-2 or 2x-2?

Alot of people got 32? Which is what I got. I just put it cause it was the last minute. I put lots of working out (breaking down the 5 marks) You get 1/2 marks for just the answer i'd say.
