Factor out common numbers.

3x - 3y = 3(x - y)

3(x - y) is your answer

Check: Distribute the number outside to all terms within the parenthesis.

3(x) = 3x

3(-y) = -3y

3x - 3y ~


~

It can be 3(x - y)

because if you simplify them you can say 3x - 3y because when you multiply, you can do like that. Sorry for my English Idk English very well
