Optima Learn · Accepted Answer

Sure! We can solve it without explicitly introducing new variables for substitution. We are given m 2n 2m n 27 and we want to maximize 2m-3n Because m and n are integers, both m 2n and 2m n are going to be integers. Factor pairs of 27 including negatives are 1,27 , 3,9 , 9,3 , 27,1 , -1,-27 , -3,-9
