Chapter 9 - Basic Algebra - 9.6 Solving Equations - 9.6 Exercises: 79

Answer

$a=-\frac{5}{4}$

Work Step by Step

We are given the equation $\frac{1}{2}-\frac{3}{4}=\frac{a}{5}$. To solve, we must first combine like terms on the left side. $\frac{1}{2}-\frac{3}{4}=\frac{1\times2}{2\times2}-\frac{3}{4}=\frac{2}{4}-\frac{3}{4}=\frac{2-3}{4}=-\frac{1}{4}=\frac{a}{5}$ Multiply both sides by 5. $-\frac{1}{4}\times5=-\frac{5}{4}=(\frac{a}{5}\times5)=a$ $a=-\frac{5}{4}$
