Step-by-step explanation:

Step 1: Define

3x + 10 = 4

2 + 5x

Step 2: Solve for x

  1. Subtract 10 on both sides:                    3x = -6
  2. Divide 3 on both sides:                         x = -2

Step 3: Evaluate

  1. Substitute in x:                    2 + 5(-2)
  2. Multiply:                               2 - 10
  3. Subtract:                              -8
