Answer:
2 liters
Step-by-step explanation:
Let
x ----> amount of the orange juice originally in the container in liters
we know that
The amount of the orange juice originally in the container multiplied by 3/8 must be equal to 3/4 of a liter of orange juice
so
The linear equation that represent this situation is

solve for x

Answer:
These expressions are both correct because they are equivalent to each other.
5(4) + 7(4) = 20 + 28 = 48
(12 x 8)/2 = 96/2 = 48
