Chapter 4.3, Problem 7CYU

To determine

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

Answer to Problem 7CYU

On solving equation, $a=1.44$

Explanation of Solution

Given information:Equation is $0.53+a=1.97$

Calculation:

Equation is given as

  $0.53+a=1.97$

On solving above equation,

  $\begin{array}{l}a=1.97-0.53\\ a=1.44\end{array}$

In order to check the solution, substitute $a=1.44$ in the given equation

Left hand side of equation is

  $\begin{array}{l}\Rightarrow 1.44+0.53\\ \Rightarrow 1.97\end{array}$

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

Hence, $a=1.44$ is solution of the equation $0.53+a=1.97$

Graphing $a=1.44$ on number line,

Let y-axis is represented as a-axis

Conclusion:

Hence, solution of equation is $a=1.44$
