Explanation:

Step 1: Define

6x + 4 = 5x + 17 + 120

Step 2: Solve for x

  1. Combine like terms: 6x + 4 = 5x + 137
  2. Isolate x terms: x + 4 = 137
  3. Isolate x: x = 133

Step 3: Check

Plug in x into the original equation to verify it's a solution.

  1. Substitute in x: 6(133) + 4 = 5(133) + 17 + 120
  2. Multiply: 798 + 4 = 665 + 17 + 120
  3. Add: 802 = 682 + 120
  4. Add: 802 = 802

Here we see that 802 does indeed equal 802.

∴ x = 133 is the solution to the equation.
