Answer:

40-9x+4x+5=

45-5x

You can't do anything else because the variables are different.

Answer:

-5x + 45

Step-by-step explanation:

40 - 9x + 4x + 5

you combine like terms

Coefficient + Coefficient ( -9x + 4x)

and

Constant + Constant ( 40 + 5 )

-5x + 45

since there isn't an equal sign you can't solve for x and this is as close as you can get to solved without knowing what x is
