Question

Solve for q: 6n-5p/11t=c

Answer 1

Your question can be interpreted in two ways, I will solve both you then take the one you mean. Also there is no q in your equation, but I suppose you mean p.
$\frac{6n-5p}{11t} =c \\ 6n-5p=11ct \\ 6n-11ct=5p \\ p= \frac{6n-11ct}{5}$
Alternatively,
$6n- \frac{5p}{11t} =c \\ 66nt-5p=11ct \\ 66nt-11ct=5p \\ p= \frac{66nt-11ct}{5}$
