Equality Properties

Step-by-step explanation:

Step 1: Define Equation

72 = 5x + 22

Step 2: Solve for x

  1. Subtract 22 on both sides:                   50 = 5x
  2. Divide 5 on both sides:                         10 = x
  3. Rewrite:                                                  x = 10

Step 3: Check

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

  1. Substitute in x:                    72 = 5(10) + 22
  2. Multiply:                               72 = 50 + 22
  3. Add:                                     72 = 72

Here we see that 72 does indeed equal 72.

∴ x = 10 is the solution to the equation.
