Question

Solve the equation. Check your solution.

$n-72=72$

Short answer

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

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

$n=144$

.Verification of our solution

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

On substituting, we get

$\begin{array}{c}n-72=72\\ 144-72=72\\ 72=72\end{array}$

. Conclusion

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