Question

Y= -2x-2, -2x+4y=12 please help i'll give 100 points.


solve it in substitution

Answer 1

x = -2 and y= 2

Explanation:

y=-2x-2 and -2x+4y=12

Substitute: -2x+4(-2x-2)=12

Distribute: -2x-8x-8=12

Combine like terms: -10x-8=12

Simplify: -10x=20

20/-10 = -2

Use that value to solve for y

y=-2x-2

Substitute x value: y=-2(-2)-2

Simplify: y=2
