• Equality Properties

Explanation:

Step 1: Define equation

3(x + 8) = 30

Step 2: Solve for x

1. Divide 3 on both sides: x + 8 = 10
2. Subtract 8 on both sides: x = 2

Step 3: Check

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

1. Substitute in x: 3(2 + 8) = 30
2. Add: 3(10) = 30
3. Multiply: 30 = 30

Here we see that 30 does indeed equal 30.

∴ x = 2 is a solution of the equation.
