3(x + 8) = 2x - 9
<em><u>Distributive property.</u></em>
3x + 24 = 2x - 9
<em><u>Subtract 24 from both sides.</u></em>
3x = 2x - 33
<em><u>Subtract 2x from both sides.</u></em>
x = -33 (this is your answer)
We can plug this value into the original equation to verify if it's correct.
3(x + 8) = 2x - 9
3(-33 + 8) = 2 * -33 - 9
-75 = -75 √ this is correct

Answer:
x = 2
General Formulas and Concepts:
<u>Pre-Algebra</u>
- Order of Operations: BPEMDAS
- Equality Properties
Step-by-step explanation:
<u>Step 1: Define equation</u>
-3(x - 1) = x - 5
<u>Step 2: Solve for </u><em><u>x</u></em>
- Distribute -3: -3x + 3 = x - 5
- Add 3x to both sides: 3 = 4x - 5
- Add 5 to both sides: 8 = 4x
- Divide 4 on both sides: 2 = x
- Rewrite: x = 2
<u>Step 3: Check</u>
<em>Plug in x to verify it's a solution.</em>
- Substitute: -3(2 - 1) = 2 - 5
- Subtract: -3(1) = -3
- Multiply: -3 = -3
Here we see that -3 does indeed equal -3.
∴ x = 2 is a solution of the equation.
