Answer:

y = 12x + 8

Explanation:

1. 3x - 1/4y = -2

Subtract 3x from both sides

2. -1/4y = -2 - 3x

The equation is in standard form.

3. -1/4y = -3x - 3

Multiply both sides by -4

4. Check photo for step 4

Divide by -1/4 = -0.25 undoes the multiplication -1/4 = -0.25

5. y = (-3x-2) / (-1/4)

Divide -2 - 3x by -1/4 = -0.25 by multiplying -2 - 3x by the reciprocal of -1/4 = -0.25

y = 12x + 8

3x - 1/4y = -2 (1/4 is a fraction, solve for y)-example-1
