Answer:
x = 7
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
7x - 6 = 8 + 5x
<u>Step 2: Solve for </u><em><u>x</u></em>
- Subtract 5x on both sides: 2x - 6 = 8
- Add 6 to both sides: 2x = 14
- Divide 2 on both sides: x = 7
<u>Step 3: Check</u>
<em>Plug in x into the original equation to verify it's a solution.</em>
- Substitute in <em>x</em>: 7(7) - 6 = 8 + 5(7)
- Multiply: 49 - 6 = 8 + 35
- Subtract/Add: 43 = 43
Here we see that 43 does indeed equal 43.
∴ x = 7 is a solution of the equation.
The fully factored form of this expression would be
(A-5)(A+4).
