1) Simplify the following: 9r + 8 - 4r - 6

2) Simplify the following:

2(x + 3y)

(I know you can’t add some of them because of their variables, but I want the simplified version)

Step-by-step explanation:

ok so for number 1 you first have to group the like terms therefore you will now have:

9r-4r+8-6

and now you calculate:

9r-4r=5r

8-6=2

so that means 5r-2 is simplied version for no.1

for number you 2 you first multiply why is inside the brackets by what is in the outside:

2(x+3y)

2x+6y (simplified version)

hope this helps! no problem

easy math just plug in a and b
