Question

Solve each of the following equations by using inverse operations.

$10+\mathrm{c}=23$

Answer 1

$\Rightarrow 10+c=23$

Adding $-10$ on both sides

$$\begin{gathered} \Rightarrow 10+\mathrm{c}+(-10)=23+(-10) \\ \Rightarrow 10+\mathrm{c}-10=13 \\ \Rightarrow \mathrm{c}=13 \end{gathered}$$

Hence, the solution is $\mathrm{c}=13$
