Step 2: Eliminate the fractions by finding a common denominator
Both coefficients of x—3/4 and 7/8—are fractions. To simplify, express them with a common denominator (8):
- 3/4 = 6/8
- 7/8 already has denominator 8
Rewriting the equation:
(6/8)x + 10 = (7/8)x
Step 3: Subtract (6/8)x from both sides
