Equality Properties

Explanation:

Step 1: Define Equation

6(x - 1) = -72

Step 2: Solve for x

1. Divide 6 on both sides: x - 1 = -12
2. Add 1 to both sides: x = -11

Step 3: Check

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

1. Substitute in x: 6(-11 - 1) = -72
2. Subtract: 6(-12) = -72
3. Multiply: -72 = -72

Here we see that -72 does indeed equal -72.

∴ x = -11 is a solution to the equation.
