Answer:
C) 14
Explanation:
Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other.
Multiply -2 to both sides of the equation. Note that, when multiplying two negative numbers, your outcome will be positive:
(-2)((-1/2)x) = (-7)(-2)
x = -7 * -2
x = 14
C) 14 is your answer.
