Set up a new equation of 5x=4x+24 and solve it should be x=24
Answer:
32 days
Step-by-step explanation:
Assume that the jar is full initially, containing 24 oz. After how many withdrawals of 3/4 oz will the jar be empty?
24 - (3/4)n = 0, or
24 = (3/4)n, or 96 = 3n. Dividing both sides by 3, we get n = 32.
The jar will be empty after 32 days.
Answer:
solution for n is 
Step-by-step explanation:
Given an equation containing one variable n.
The equation is as follows:

To solve for n we can subtract 3/4 from both the sides
The result is

Verify:
Substitute the answer in the given equation.

Both sides equal thus proving our correctness of answer.
