Let the pants be represented by p
Let the shirts be represented by s
Equations.
28 P + 12 S = 1524 (1)
51 P + 35 S = 3065 (2)
Plan
We're going to get rid of the shirts, because we are not asked for them.
Multiply (1) by 35 and (2) by 12
Sub and Solve
35(28P + 12S = 1524)
980 P + 420S = 53340 (1a)
12(51P + 35S = 3065)
612P + 420S = 36780 (2a)
Subtract 2a from 1a I'm going to leave the mechanics to you. But I will show the results.
368 P = 16560 Divide by 368
P = 16560 / 368
P = 45
Each pair of pants sold for 45 dollars.<<<<<
