Question

question 9 of 10
solve 8x - 2y = 12 for y.

a. y = 4x - 6
b. y = 8x + 6
c. y = 4x - 12
d. y = -8x + 12

Explanation:

Step1: Isolate the y-term

Subtract $8x$ from both sides.
$8x - 2y - 8x = 12 - 8x$
$-2y = -8x + 12$

Step2: Solve for y

Divide all terms by $-2$.
$y = \frac{-8x}{-2} + \frac{12}{-2}$

Answer:

A. $y=4x-6$
