Answer: y = 3
Explanation:
Our task is to find the number, given that:
Nine less than 4 times a number equals that number.
So first, let y be our number.
Then:
4 times y => 4y
9 less than 4y => 4y - 9
It equals that number: 4y - 9 = y
So now, we have an equation that we can solve for y.
First, add 9 to both sides:

Then, subtract y from both sides:

Lastly, divide both sides by 3:
