4 + 9xy - 18 - 2x

Please note that Rosala has simplified this expression.

It cannot be solved because it is not equal to anything  

So to solve this we just have to get the like terms together!in this expression we dont have many like terms but just two which are 4 and -18 , so lets get them together and solve!

4 + 9xy - 18 - 2x

=9xy -18 +4 -2x      ( and now out here we would subtract -18 and 4 and so this will give us our answer)

=9xy - 14 - 2x    ( now we just have to plave these in their correct places)

= 9xy -2x -14   ANSWER

So now your not an anonymous user so i hope u know what i always say at this point and hope u know what to do if u dont uderstand this!

hope this helps!
