Answer:

y = 13.5

x = 51/-6 -> (-8.5)

Step-by-step explanation:

y = -3x - 12

-6x - 27 = 24

-6x = 51              first solve your first equation for x

x = 51/-6

y = -3(51/-6) - 12               substitute in your x value into the other equation

y = 13.5

make sure to check that your answers match up to make the equation true
