Complete factoring

3y+30=3 ()

can someone explain this to me

Factoring requires taking out a value out of the expression which result to an expression where the factors are shown. We factor the given expression above as follows:

3y+30

3 (3y/3 - 30/3)

3 (y - 10)

When you distribute 3 into the parenthesis again you will still obtain the same initial expression. Hope this answers the question. Have a nice day.
