Question

3. What is the value of the x in the solution to the system of linear equations below?

y = 8x − 8
3x + 2y = −16

A x = 0
B x = 2
C x = −5
D x = −8

Answer 1

B x = 2

Explanation:

Step 1: Add -2y to both sides.

−75x+2y+−2y=−16+−2y

−75x=−2y−16

Step 2: Divide both sides by -75.

−75x /−75 = −2y−16 −/75

x= 2 /75 y+ 16 /75

Answer:

x= 2 /75 y+ 16 /75

Answer 2

x=0

Explanation:

3x+2(8x-8)=-16 plug the 1st y for the 2nd y

----------------------------------------------

3x+16x-16=-16 distribute the 2

--------------------------------------------

19x -16 = -16 combine like terms

+16 +16 add 16 both sides

--------------------------------------------

19x=0

19 19 divide 19 both sides

x=0
