Answer:
[tex]p = \frac{q-5r}{2}[/tex]
Step-by-step explanation:
[tex]2p + 5r = q[/tex]
We need to solve the equation for p
Our aim is to get p alone
[tex]2p + 5r = q[/tex]
Subtract 5r on both sides
[tex]2p + 5r-5r = q-5r[/tex]
[tex]2p= q-5r[/tex]
Now divide both sides by 2 to get 'p' alone
[tex]\frac{2p}{2} = \frac{q-5r}{2}[/tex]
[tex]p = \frac{q-5r}{2}[/tex]
