Question

Solve for p in the literal equation 2p + 3r = q.
P =

Answer 1

`p = ( q - 3r )/( 2)`

Explanation:

2p + 3r = q

2p + 3r - 3r = q - 3r [ subtract 3r from both sides ]

2p + 0 = q - 3r [ -3r + 3r = 0 ]

2p = q - 3r

`(2p)/(2) = (q-3r)/(2)` [ divide by 2 on both sides ]

`p = ( q - 3r )/( 2)`
