Answer

b = \frac{29}{18} Explanation 1. Eliminate fractions by finding a common denominator Multiply every term by 24 (LCM of 8, 4, and 12): 24 \times \frac{5}{8} = 15, 24 \times \frac{3}{4}b = 18b, 24 \times \frac{7}{12} = 14. 2. Simplify the equation The equation becomes 15 = 18b - 14. 3. Isolate the variable b Add 14 to both sides: 15 + 14 = 18b. Thus, 29 = 18b. 4. Solve for b Divide both sides by 18: b = \frac{29}{18}.

Explanation

1. Eliminate fractions by finding a common denominator<br /> Multiply every term by 24 (LCM of 8, 4, and 12): $24 \times \frac{5}{8} = 15$, $24 \times \frac{3}{4}b = 18b$, $24 \times \frac{7}{12} = 14$.<br />2. Simplify the equation<br /> The equation becomes $15 = 18b - 14$.<br />3. Isolate the variable $b$<br /> Add 14 to both sides: $15 + 14 = 18b$. Thus, $29 = 18b$.<br />4. Solve for $b$<br /> Divide both sides by 18: $b = \frac{29}{18}$.
