You can put this solution on YOUR website! A+B= 127 subtract B from both sides:
A= 127-B We'll use this value for A next.
5.50A+4.30B = 607.30 Now substitute for A:
5.50(127-B)+4.30B = 607.30
698.5-5.50B+4.30B = 607.30 Now subtract 698.5 from both sides and subtract B on left:
-1.2B = -91.20 Now divide both sides by -1.2 (and remember: -/- = +)
B = 76 pounds. And:
127-76 = 51 pounds are type A
