Answer:
x = -8
Explanation:
To solve for x, you want to isolate it (meaning it's the only thing on that side of the equation). To begin, subtract 3 from both sides this'll leave you with
1/2x = -4
To get rid of the 1/2 in front of x, you need to multiply it (both sides of the equation) by the reciprical.
(2)1/2x = -2(2)
x = -8
