3. $\frac{3}{4}-\frac{1}{2}n=\frac{5}{8}$
3. $\frac{3}{4}-\frac{1}{2}n=\frac{5}{8}$
Answer
Explanation:
Step1: Isolate the term with n
Subtract $\frac{3}{4}$ from both sides. $\frac{3}{4}-\frac{1}{2}n-\frac{3}{4}=\frac{5}{8}-\frac{3}{4}$ $-\frac{1}{2}n=\frac{5}{8}-\frac{6}{8}$ $-\frac{1}{2}n=-\frac{1}{8}$
Step2: Solve for n
Multiply both sides by - 2. $n = (-\frac{1}{8})\times(-2)$ $n=\frac{1}{4}$
Answer:
$n=\frac{1}{4}$
