<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
5x - 8(1 + 7x) = -8
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -8: 5x - 8 - 56x = -8
- Combine like terms: -51x - 8 = -8
- Isolate <em>x</em> term: -51x = 0
- Isolate <em>x</em>: x = 0
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it is a solution.</em>
- Substitute in <em>x</em>: 5(0) - 8(1 + 7(0)) = -8
- Multiply: 0 - 8(1 + 0) = -8
- Add: -8(1) = -8
- Multiply: -8 = -8
Here we see that -8 does indeed equal -8.
∴ x = 0 is a solution of the equation.
