Answer:
x = 1
Step-by-step explanation:
Step 1: Write equation
-5(2x - 5) - 3x - 5 = 7
Step 2: Solve for <em>x</em>
- Distribute -5: -10x + 25 - 3x - 5 = 7
- Combine like terms: -13x + 20 = 7
- Subtract 20 on both sides: -13x = -13
- Divide both sides by -13: x = 1
Step 3: Check
<em>Plug in x to verify it's a solution.</em>
-5(2(1) - 5) - 3(1) - 5 = 7
-5(2 - 5) - 3 - 5 = 7
-5(-3) - 8 = 7
15 - 8 = 7
7 = 7
