Step-by-step 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.

Answer:

x = - 11

Step-by-step explanation:

Given

6(x - 1) = - 72 ← divide both sides by 6

x - 1 =  - 12 ( add 1 to both sides )

x = - 11
