hi! i’m having trouble with these and don’t really know how to solve them. i’d really appreciate some help ^^
1. Combine like terms. What is a simpler form of the expression?
-3(-4y+3)+7y
2. Evaluate the expression for the given value of the variable(s).
5a+5b; a = -6, b = -5
thank you so much in advance! :)
-3(-4y+3)+7y
12y - 9 + 7y
19y - 9
5a+5b; a = -6, b = -5
-30 + -25 = -55
