Question

Solve for the indicated variable: 2p + 5r = q for p

Answer 1

2p+5r=q , solve for p
2p=q-5r
p=q-5r/2

Answer 2

`p = (q-5r)/(2)`

Explanation:

`2p + 5r = q`

We need to solve the equation for p

Our aim is to get p alone

`2p + 5r = q`

Subtract 5r on both sides

`2p + 5r-5r = q-5r`

`2p= q-5r`

Now divide both sides by 2 to get 'p' alone

`(2p)/(2) = (q-5r)/(2)`

`p = (q-5r)/(2)`
