Chapter 4.3, Problem 4CYU

To determine

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

Answer to Problem 4CYU

On solving equation, $x=48$

Explanation of Solution

Given information:Equation is $x+24=72$

Calculation:

Equation is given as

  $x+24=72$

On solving above equation,

  $\begin{array}{l}x=72-24\\ x=48\end{array}$

In order to check the solution, substitute $x=48$ in the given equation

Left hand side of the equation is

  $\begin{array}{l}\Rightarrow 48+24\\ \Rightarrow 72\end{array}$

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

Hence, $x=48$ is solution of the equation $x+24=72$

Graphing $x=48$ on number line,

Conclusion:

Hence, solution of equation is $x=48$
