1. Evaluate the expression for the given value of the variable(s).

 

5a + 5b; a= –6, b = –5 

 

 

 

 

2. Combine like terms. What is a simpler form of the expression?

 

–3(–4y + 3) + 7y

5*(-6)+5*(-5)

-30   +  -25= -55

(probably wrong, never confident in the math dept. lol)

-3*-4y=12y

-3*3=-9

12y+(-9)+7y

12y+7y=19y

19y-9
