Question

2x + 4 = 16
O A. x = 24
O B. x = 40
O c. x = 6
O D. x = 10

Answer 1

C. x = 6

Explanation:

You are solving for x. Isolate the variable, x. Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

First subtract 4 from both sides:

2x + 4 (-4) = 16 (-4)

2x = 16 - 4

2x = 12

Next, isolate the variable, x. Divide 2 from both sides:

(2x)/2 = (12)/2

x = 12/2

x = 6

C. x = 6 is your answer.
