Given the expression:
[tex]5+(-7x)+8y+3y[/tex]We can only add the similar terms, in this case they are 8y and 3y. Also remember that if a plus sign is outside of a parenthesis, then the contents of the parenthesis remain with the same sign:
[tex]5+(-7x)+8y+3y=5-7x+11y[/tex]therefore, the simplified expression is 5-7x+11y
