Question

Solve for m. m/2 - √5=3

Answer 1

$\frac{m}{2}-\sqrt{5}=3$

add √5 on both sides,

$\begin{gathered} \frac{m}{2}-\sqrt{5}+\sqrt{5}=3+\sqrt{5} \\ \frac{m}{2}=3+\sqrt{5} \end{gathered}$

multiply by 2 on both idesm and simplify,

$\begin{gathered} \frac{m}{2}\times(2)=2\times(3+\sqrt{5}) \\ m=6+2\sqrt{5} \end{gathered}$

Answer:

$m=6+2\sqrt{5}$
