Answer:
y =
Step-by-step explanation:
Given
y = 3xy - 1
Collect terms in y on the left side by subtracting 3xy from both sides
y - 3xy = - 1 ← factor out y on the left side
y(1 - 3x) = - 1 ( divide both sides by 1 - 3x
y = ← multiply numerator/denominator by - 1
y =
Answer:
2 possible values
Step-by-step explanation:
The given expression is:
In order for this to result in a whole number, 144/y must be a perfect cube, the possible perfect cubes (under 144) are:
1, 8, 27, 64, 125
The values of y that would result in those numbers are:
Only two values of y are integers, therefore, there are only two possible values of y for which the given expression results in a whole number.
