**drwls**, Monday, May 3, 2010 at 6:01amLet X = cake weight

Let Y = cherry weight

Let Z = apple weight

2X = Y + Z

Z = 5Y + X

Eliminate the variable X to get an equation between Y and Z.

2X = -10Y +2Z (from the second equation, multiplied by two and rearranged)

15Y -Z = 0

Z = 15 Y

15 cherries weight the same as an apple.
