Combine like terms. Like terms are terms that are the same excluding coefficients.

-b+2b=b
-5x-4x=-9x
-3+7=4

Put it all together
Final answer: b-9x+4

Solve for x: −3(x + 3) = −3(x + 1) − 5.
erastova [34]
-3(x+3)= -3(x+1)-5
-3x+9=-3x+3-5 
so you would have just distributed then you combine like terms and get
-3x+9=-3x-2
then add two to both sides and get
-3x+9=-3x-2
-3x+2=-3x+2
-3x+11=-3x
+3x+11=+3x
0x+11=0x 
so 11+0x 
divide both by zero and you get x+0
