How many of each color bikes are there if there are 18 bikes in a bike rack 4 more blue bikes than yellow bikes and 2 less yellow bikes than green?
18-6= 12 ..... 12-6=6 so we now have equal parts of all 3 colors: 6 blue, 6 yellow and 6 green. We know we have 2 less yellow than green so 6-2= 4 yellow We also know there are 4 more blue than yellow so 4+4 = 8 blue We had 6 green in our original problem, so we still have 6 green bikes. After subtraction we have 4 yellow bikes and after addition we have 8 blue bikes. 8 blue bikes 6 green bikes 4 yellow bikes 8+6+4 = 18 You could use division and/or algebra to solve this, but only addition and subtraction have been used to keep the process simple.
