Hello!

Expression: 15y - 3(4y + 10)

The first step is to distribute.To do this we have to multiply the number that is before the brackets separately by all the number in the bracket. 

15y + (-3)(4y) (-3)(10) 
15y + -12y + -30
 

Next we will combine like terms: 

15y + -12y + -30(15y + -12y(-30) 
3y + -30

The terms we combined are: (15y + -12y)

Final answer: 3y - 30

Hope I helped you! (:
