Chapter 4.3, Problem 15PPS

To determine

To calculate:To solve the equation, then check your solution and graph it on number line

Answer to Problem 15PPS

On solving equation, $p=32$

Explanation of Solution

Given information:Equation is $-31=r-36$

Calculation:

Equation is given as

$-31=r-36$

On solving above equation,

> $\begin{array}{l}r-36=-31\\ r=-31+36\\ r=5\end{array}$

In order to check the solution, substitute $r=5$ in the given equation

$\begin{array}{l}LHS:32-12\\ LHS:20\end{array}$

Now, LHS = RHS

Hence, $r=5$ is solution of the equation $-31=r-36$

Graphing $r=5$ on number line,

Let y-axis is represented as r-axis
