Answer:

x = 9

General Formulas and Concepts:

<u>Pre-Algebra</u>

  • Order of Operations: BPEMDAS
  • Equality Properties

Step-by-step explanation:

<u>Step 1: Define equation</u>

0.8x = 7.2

<u>Step 2: Solve for </u><em><u>x</u></em>

  1. Divide both sides by 0.8:                    x = 9

<u>Step 3: Check</u>

<em>Plug in x to verify it's a solution.</em>

  1. Substitute:                    0.8(9) = 7.2
  2. Multiply:                        7.2 = 7.2

7.2 does indeed equal 7.2. ∴ x = 9 is a solution.

And we have our final answer!
