Explanation:

In order to verify x, simply plug it back into the original equation to see if the equation would be true.

Step 1: Define

Original Function: x + 2x + 3 = 4x - 12

x = 15

Step 2: Verify

  1. Substitute:                    15 + 2(15) + 3 = 4(15) - 12
  2. Multiply:                        15 + 30 + 3 = 60 - 12
  3. Add:                              48 = 60 - 12
  4. Subtract:                       48 = 48

Since 48 does indeed equal to 48, 15 would be a solution. Therefore, x = 15 is verified and true.
