Answer:

The answer to this equation would be B. 6!

Explanation:

  1. 2x + 3 = 15
  2. Subtract 3 from left and right side. Variable needs to be left alone. 15 will turn into 12.
  3. 2x = 12
  4. x= 6 since 2 x 6 = 12 or divide 12 by 2 and get 6

Check Answer:

2(6) + 3 = 15

2x6 =12

12 + 3 =15
