Answer:
x = -60
Step-by-step explanation:
8x - 3 (4x + 8) = 216 [Write the Equation]
8x - 12x - 24 = 216 [Multiply the 4x and the 8 by -3]
-4x - 24 = 216 [Add the 8 and -12 together]/[Combine like Terms]
-4x = 240 [Get 'x' variable alone]/[Use Inverse Operation to get rid of -24]
x = -60 [Divide both sides by -4 to get value of 'x']
I hope I explained it well enough for you to learn to do it on your own.
