Chapter 2: Q. 198 (page 240)

In the following exercise, solve the following equations with variables and constants on both sides.
$8 x - 15 = 7 x + 3$

Short Answer

Expert verified

The simplified value is $x = 18$

Step by step solution

Step 1. Given information

Given equation is $8 x - 15 = 7 x + 3$

We have to solve the given equation.

Step 2. Explanation

$\begin{array}{l} \Rightarrow 8 x - 15 = 7 x + 3 \\ \Rightarrow 8 x - 7 x - 15 = 7 x - 7 x + 3 (Subtract 7 x form both the sides) \\ \Rightarrow x - 15 = 3 (Simplify) \\ \Rightarrow x - 15 + 15 = 3 + 15 (Add 15 to both the sides) \\ \Rightarrow x = 18 (Simplify) \\ Thesimplfiedvalueisx=18 \end{array}$
