**Reiny**, Sunday, January 13, 2013 at 9:06amnumber of tomatoes --- x

number of peppers ---- y

number of eggplants --- z

x+y+z = 81 (#1)

35x + 20y + 30z = 2185

or

7x + 4y + 6z = 437 (#2)

x+y = (1/2)z

2x + 2y = z (#3)

plug #3 into #1

x+y+2x+2y=81

3x + 3y=81

x+y = 27 --- or y = 27-x ---- #4

plug #3 into #2

7x + 4y + 6(2x+2y) = 437

19x + 16y = 437 --- #5

sub #4 into #5

19x + 16(27-x) = 437

3x = 5

uggghhhh, x should be a whole number

either I made an arithmetic error or the question is bogus.
