Answer:
x = -7
Step-by-step explanation:
Get x by itself by combining like terms
8x + 12 = 4 x - 16
Subtract 12 from both sides
8x = 4x - 28
Subtract 4x from both sides
4x = -28
Divide both sides by 4 to get rid of the coefficient so we know what x alone is equal to, instead of what we have currently which shows what 4 x's equals
x = -28/4
x = -7
Understanding the answer
1x = - 7
One x is equal to - 7 units.
