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.
