Step-by-step explanation:

y + 2 = -3(x - 4)

Simplify this equation first

y +2 = -3(x - 4)

Distribute the -3

y + 2 = -3x - (-12)

y + 2 = -3x + 12

  -2             -2

y = -3x + 10

Now that it is written in y = mx + b form, plug in the y value it gave you

-2 = -3x + 10

-10          -10

-12 = -3x

Divide both sides by -3

4 = x

x = 4
