Answer:
x value would be 2
Step-by-step explanation:
The computation is shown below:
Given that
x^2 + 2x = 8
x^2 + 2x - 8 = 0
x^2 + 4x - 2x - 8 = 0
x(x + 4) - 2(x + 4) = 0
(x - 2) (x + 4) = 0
So, x value would be 2
x - 2 = 0
x = 2
Answer:c
Step-by-step explanation: i think hope this helps
First add like terms
53 = -14 + 7z
now add 14 to both sides
67 = 7z
divide both sides by 7
9.5714285 = z
i hope this helps!!
Answer:
