Solve for the specified variable.
S =
solve for p
S = ; multiplied what's inside the bracket
:
S(q + p - pq) = p; divided both sides by (q+p-pq)
:
q + p - pq = ; divided both sides by S
:
q + p - pq - = 0; subtract from both sides
:
p - pq - = -q; subtract q from both sides
:
p(1 - q - ) = -q; Factor out p
:
p = ; divide both sides by (1 - q - (1/S))
