Answer:
x = -5/21
Step-by-step explanation:
Step 1: Write equation
2(12x - 1) = (21x - 49)/7
Step 2: Solve for <em>x</em>
- Multiply both sides by 7: 14(12x - 1) = 21x - 49
- Distribute 14: 168x - 14 = 21x - 49
- Subtract 21x on both sides: 147x - 14 = -49
- Add 14 to both sides: 147x = -35
- Divide both sides by 147: x = -5/21
