There were two containers of oil. there was twice as much oil in the second container as in the first one. after using 13 liters of oil from the first container and 7 liters from the second one, the second container still had 3 times more oil than the first one. how many liters of oil in total were in both containers originally?
will mark brianleist answer

The total liters of oil in the first container originally was 32 liters

total liters of oil in the second container originally was 64 liters

Step-by-step explanation:

Let

x> total liters of oil in the first container originally

y> total liters of oil in the second container originally

we know that

y=2x > equation A

(y-7)=3(x-13) > equation B

substitute equation A in equation B

(2x-7)=3(x-13)

2x-7=3x-39

3x-2x=39-7

x=32 liters

Find the value of y

y=2(32)=64 liters

answer:

a=9
