Chapter 4.3, Problem 12PPS

To determine

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

Answer to Problem 12PPS

On solving equation, $p=32$

Explanation of Solution

Given information:Equation is $p-12=20$

Calculation:

Equation is given as

$p-12=20$

On solving above equation,

> $\begin{array}{l}p=20+12\\ p=32\end{array}$

In order to check the solution, substitute $p=32$ in the given equation

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

Now, LHS = RHS

Hence, $p=32$ is solution of the equation $p-12=20$

Graphing $p=32$ on number line,

Let y-axis is represented as p-axis
