Step-by-step explanation:

Step 1: Define equation

3x + 5 = 2x - 1

Step 2: Solve for x

  1. Subtract 2x on both sides:          x + 5 = -1
  2. Subtract 5 on both sides:            x = -6

Step 3: Check

Plug in x to verify it's a solution.

  1. Substitute:                    3(-6) + 5 = 2(-6) - 1
  2. Multiply:                        -18 + 5 = -12 - 1
  3. Add/Subtract:               -13 = -13
