      (Show Source): 
You can put this solution on YOUR website! X+Y=98 X=Y+16
 (Y+16)+Y=98
 2Y=98-16
 2Y=82
 Y=82/2
 Y=$41 IS THE PRICE OF THE SHOES.
 98-41=$57 IS THE PRICE OF THE SWEATER.
 PROOF:
 57=41+16
 57=57
 ********************************************
 LET X BE THE COMMISSION & Y BE THE SALARY.
 3,000X+Y=850
 4,000X+Y=1,000 SUBTRACT.
 -----------------------------
 -1,000X=-150
 X=-150/-1,000
 X=.15 OR 15 % IS THE COMMISSION ON SALES.
 3,000*.15+Y=850
 460=Y=850
 Y=850-450
 Y=$400 IS THE SALARY.
 PROOF:
 4,000*.15+400=1,000
 600+400=1,000
 1,000=1,000
