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
