Solve for S, V, J and P?

1/(3S) − p/4 = 0

1/(3V) − p/2 = 0

1/(3J) − p/12 = 0

S/4 + V/2 + J/12 − 4 = 0

Update:

I would appreciate a step by step approach.

    I'd start by rewriting each equation to get rid of the fractions.

    3PS = 4

    3PV = 2

    PJ = 4

    3S + 6V + J = 48

    Multiply the last equation by P and substitute values from the other three equations.

    4 + 4 + 4 = 48P

    solve for P, then use that value to solve for each other variable.
