We'd need a value, a coefficient, that effectively tosses away the variable "y" and leaves "x" all by her lonesome.
and our sharpest value for that, is our very good friend Mr Zero, c = 0, cy = 0y = 0.
check the picture below.
15 and a half (15.5) quarts
Get each in common units
Orange 2 gallons X 4 quart per gallon = 8 quarts
Pineapple 4 quarts no change
Cranberry 3 pints / 2 pints per quart = 1.5 quarts
Apple 8 cups / 4 cups per quart = 2 quarts
Add them all together 8+4+1.5+2=15.5
You should be able to set up a proportion between the sides something like (18+x)/x=(56+21)/56
The two equivalent expressions are 3(3x+2y) and 9x+6y.
To get these answers, first simply the expressions within the brackets to give 3(3x+2y). Then expand for 9x+6y.
Answer:
