Answer by elima(1433) About Me  (Show Source):
You can put this solution on YOUR website!
(2x+x-2)+(-3x+4x+8) and (5-5x)+(-3+3x+x)
First solve each equation in the paranthesis;
(2x+x-2)=3x-2
(-3x+4x+8)=x+8
Then but the equations together;
3x-2+x+8
Now add or subtract like terms;
4x+6
(5-5x)= you leave this one as is because there are no like terms;
(-3+3x+x)=-3+4x
Now put equations together;
5-5x-3+4x
Add or subtract like terms;
2-x
Hope you understand
