Step-by-step explanation:

Step 1: Define equation

5x + 2 = 20

Step 2: Solve for x

1. Subtract 2 on both sides:                    5x = 18
2. Divide 5 on both sides:                        x = 18/5

Step 3: Check

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

1. Substitute in x:                    5(18/5) + 2 = 20
2. Multiply:                               18 + 2 = 20
3. Add:                                     20 = 20

Here we see that 20 does indeed equal 20.

∴ x = 18/5 is a solution to the equation.
