Chapter 2: Q. 18E (page 93)

Solve the equation. Check your solution.
$n - 72 = 72$

Short Answer

Expert verified

Solution of given equation is $n = 144$ .

Step by step solution

Step 1 .Solving for value of n

$n - 72 = 72$

Adding72 on both sides, we get

$\begin{matrix} n - 72 = 72 \\ n - 72 + 72 = 72 + 72 \\ n = 72 + 72 \\ n = 144 \end{matrix}$

$n = 144$

.Verification of our solution

For checking our answer, substitute $n = 144$ in given equation $n - 72 = 72$ .

On substituting, we get

$\begin{matrix} n - 72 = 72 \\ 144 - 72 = 72 \\ 72 = 72 \end{matrix}$

. Conclusion

Here, as both sides above expression are equal, our answer is true.
