(Show your work)
4x+y=9
3x+2y=8

Answer 1

(2,1)

Explanation:

1 step: -2(4x+y=9)

3x+2y=8

2 step: -8x-2y=-18

3x+2y=8

3 step: -5x=-10

divide by -5 both sides

x=2

Now we solve for y

choose an equation from above and subtitute the x for 2.

3(2)+2y=8

6+2y=8

subtract 6 from both sides

2y=2

Y=1
