Chapter 4.3, Problem 5CYU

To determine

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

Answer to Problem 5CYU

On solving equation, $p=-32$

Explanation of Solution

Given information:Equation is $p-13=-45$

Calculation:

Equation is given as

  $p-13=-45$

On solving above equation,

  $\begin{array}{l}p=-45+13\\ p=-32\end{array}$

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

Left hand side of the equation is:

  $\begin{array}{l}\Rightarrow -32-13\\ \Rightarrow -45\end{array}$

Now, left hand side of equation is equal to right hand side.

Hence, $p=-32$ is solution of the equation $p-13=-45$

Graphing $p=-32$ on number line,

Let y-axis is represented as p-axis

Conclusion:

Hence, solution of equation is $p=-32$
