Step-by-step explanation:

Step 1: Define equation

7x - 6 = 8 + 5x

Step 2: Solve for x

1. Subtract 5x on both sides:                    2x - 6 = 8
2. Add 6 to both sides:                              2x = 14
3. Divide 2 on both sides:                          x = 7

Step 3: Check

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

1. Substitute in x:                    7(7) - 6 = 8 + 5(7)
2. Multiply:                               49 - 6 = 8 + 35
3. Subtract/Add:                      43 = 43

Here we see that 43 does indeed equal 43.

∴ x = 7 is a solution of the equation.
