For this case, the first thing we will do is identify variables:
x: number of washings.
y: amount of ounces of remaining shampoo.
We write the equation taking into account:
1) bottle of shampoo contains 60 ounces
2) He used ounce of shampoo each time he washes his hair
The equation is:
y = -x + 60
Then, for y = 24 we have:
y = -x + 60
24 = -x + 60
We clear x:
x = 60-24
x = 36
