X+2y=10
2x+8y=16

x=-2y+10

2x+8y=16
2(-2y+10)+8y=16
-4y+20+8y=16
4y=-4
y=-1

x=-2y+10
x=-2(-1)+10
x=2+10
x=12

This means that there can be only one solution (12,-1).

The answer is 370 because you need to work it out.

Basically what I did was look at the first number, 12, and the answer to the equation and saw that 12 x 10 would be 120. And 360 + 10 would be 370.

It fits in perfectly.

12(370 - 360) = 120
370 - 360 = 10
12(10) = 120

So x = 370
