Answer:
x = 0.5
Step-by-step explanation:
Step 1: Write equation
7 + 3x - 12x = 3x + 1
Step 2: Solve for x
- Combine like terms: 7 - 9x = 3x + 1
- Add 9x to both sides: 7 = 12x + 1
- Subtract 1 on both sides: 6 = 12x
- Divide both sides by 12: 6/12 = x
- Simplify: 1/2 = x
- Rewrite: x = 1/2
- Evaluate: x = 0.5
Step 3: Check
Plug in x to verify it's a solution.
7 + 3(0.5) - 12(0.5) = 3(0.5) + 1
7 + 1.5 - 6 = 1.5 + 1
8.5 - 6 = 2.5
2.5 = 2.5
