#L=(A-I)/Q#

Explanation:

Please use the formatting! Writing formulas in words leads to ambiguity: you mean #Q=(A-I)/L# or #Q=A-I/L#? I'll assume the first.

We start from #Q=(A-I)/L#.

Multiply the whole expression by #L#:

#Q*L = (A-I)/cancel(L) * cancel(L)#.

Divide both terms by #Q#:

#(cancel(Q)*L)/cancel(Q) = (A-I)/Q#
