What is 90y-10x-10 in simplest form

90y - 10x - 10

First, find the greatest common factor (GCF)
10 is the largest number that divides evenly into 90y, -10x, and -10.
The GCF is 10.

Second, factor out the GCF.
Put the GCF as the first term
In parentheses, divide each term by the GCF


Third, simplify each term in the parentheses. / Your problem should look like: 10(9y - x - 1)

 10(9y - x - 1)

It’s either a or c as the answer.
