Answer:
x = -6
Step-by-step explanation:
first you want to distribute -4 throughout the parenthesis and you would get
-7 - 4x = 18
then you would add seven to negative seven and to 18, canceling out the seven already there which would leave you with
-4x = 24
then you divide -4 from both sides and get
x = -6
hope this explanation helps!
