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.

not an answer but how do you attach images because it would be more useful
Step-by-step explanation:
D=1
you add 1/2 to the other side of the equal sign which will then give you the value of d
1/2+1/2=1
Answer:
C
Step-by-step explanation:
If they y values are the same then you can equate these 2 equations
y = 8x and y = 2x + 2
8x=2x+2
because where they inersect their x and y values are the same
