Step-by-step explanation:

Step 1: Define equation

3(x - 2) = 2(x + 1)

Step 2: Solve for x

1. Distribute:                                     3x - 6 = 2x + 2
2. Subtract 2x on both sides:          x - 6 = 2
3. Add 6 to both sides:                    x = 8

Step 3: Check

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

1. Substitute in x:                    3(8 - 2) = 2(8 + 1)
2. Subtract/Add:                      3(6) = 2(9)
3. Multiply:                               18 = 18

Here we see that 18 does indeed equal 18.

∴ x = 8 is a solution to the equation.
