Question

A system of equations is shown.

Answer 1

x=4 , y=1

Explanation:

y = 2x-7

y = -x +5

Set them equal to each other

2x-7 = -x+5

add x to each side

2x+x-7 = -x+x+5

3x-7 = 5

Add 7 to each side

3x-7+7 = 5+7

3x = 12

Divide by 3

3x/3 = 12/3

x=4

Now find y

y = -x+5

y = -4 +5

y = 1
