Question

What is the solution of this linear equation see photo

Answer 1

SOLUTIION

The given equations are

$p+q+r=32,p-r=4,2p+q=36$

This further gives

Therefore the solutions are:

$p=\frac{-q+36}{2},r=\frac{36-q}{2}-4$

From the option considering the value q=8, it follows

$\begin{gathered} p=\frac{-8+36}{2} \\ p=14 \end{gathered}$

And

$\begin{gathered} r=\frac{36-8}{2}-4 \\ r=14-4 \\ r=10 \end{gathered}$

Therefore the solution is

$(14,8,10)$
