Question

Find the root: $5=x+\frac{1}{2}$

Answer 1

$5=x+\frac{1}{2}$

Rule: If a term is transposed from one side of the equation to the other, then its sign will change. $+$ changes to $-$ and vice versa and $\times$changes to $÷$ and vice versa.

$$\begin{gathered} 5-\frac{1}{2}=x \\ \frac{5\times 2-1}{2}=x \\ \frac{9}{2}=xorx=\frac{9}{2} \end{gathered}$$
