Chapter 2: Q. 115 (page 229)

In the following exercise, solve each equation requiring simplification.
$\frac{7}{8} n - \frac{3}{4} n = 9 + 2$

Short Answer

Expert verified

On simplifying, we get $n = 88 .$

Step by step solution

Step 1. Given information

$\begin{array}{l} Thegivenequationis \frac{7}{8} n - \frac{3}{4} n = 9 + 2. \\ Wehavetosimplifythegivenequation. \end{array}$

Step 2. Simplify

$\begin{array}{l} Now, \\ \Rightarrow \frac{7}{8} n - \frac{3}{4} n = 9 + 2 \\ \Rightarrow (\frac{7}{8} - \frac{3}{4}) n = 11 [Simplifyeachside] \\ \Rightarrow (\frac{7 \cdot 4 - 3 \cdot 8}{8 \cdot 4}) n = 11 \\ \Rightarrow (\frac{28 - 24}{8 \cdot 4}) n = 11 \\ \Rightarrow (\frac{4}{8 \cdot 4}) n = 11 \\ \Rightarrow 8 \times \frac{n}{8} =8 \times 11 [Multiplybothsidesby8] \\ \Rightarrow n = 88 \end{array}$
