Question

What is the value of y when x = -3 4x+2y=8

Answer 1

x=−3 and y=10

Explanation:

Let's solve your system by substitution.

x=−3;4x+2y=8

Step: Solvex=−3for x:

x=−3

Step: Substitute−3forxin4x+2y=8:

4x+2y=8

(4)(−3)+2y=8

2y−12=8(Simplify both sides of the equation)

2y−12+12=8+12(Add 12 to both sides)

2y=20

2y

2

=

20

2

(Divide both sides by 2)

y=10

(happy to help)

Answer 2

y=10

Explanation:

4(-3)+2y=8

-12+2y=8

move the -12 0ver to the 8 by adding

2y=20

divide by 2

y=10
