Question

Form a valid equation with the given solution.

$\mathrm{d}=4$

Answer 1

Given, $\mathrm{d}=4$

$\Rightarrow \mathrm{d}=4$

Adding $7$ to both sides

$$\begin{gathered} \Rightarrow \mathrm{d}+7=4+7 \\ \Rightarrow \mathrm{d}+7=11 \end{gathered}$$

Hence, $\mathrm{d}+7=11$ is the required equation.
