Help me please please help

1) 8y + 9         2) 2n + 4        3) 3d + 5h

rearrange the equations and combine like terms. combine the terms with the same variables and add / subtract them.

for example number 1:

9y - 11 + 20 - y

is the same thing as

9y - y + 20 - 11

and now you can easily combine them:

8y + 9
