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
\(10 (\frac{90y}{10} + \frac{-10x}{10} - \frac{10}{10} )\)
Third, simplify each term in the parentheses. / Your problem should look like: 10(9y - x - 1)
Answer: 10(9y - x - 1)
