HELP .-. A painter bought 16 gallons of paint, just to cover two rooms. One room is twice the size of the other room and require
givi [52]
The total number of gallons of paint needed for the big room is 3x and the number of gallons of paint needed for the small room is 2y. 
                                   3x + 2y = 16
Given the sizes of the room, the relation should be that,
                                    x = 2y
Solving the equation,
                                      3(2y) + 2y = 16
                                               y = 2
Therefore x is equal to 4 gallons. 
With the condition that only the bigger room is painted, the number of gallons of paint used should be 12 gallons and what is left should be 4 gallons.
