General Formulas and Concepts:
<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.
Answer:
11 > - 16
False, you should add 16 first to make the equation easier. If you multiplied by 4, you would have to multiply everything by 4, whereas by adding 16 first you only have to solve 27 · 4 to get a.
