Best ResponseYou've already chosen the best response.0the equation would be 75=r+w and 2r+3=w you will use substitution to solve for r and then you can solve for w.

Best ResponseYou've already chosen the best response.0you can change the second equation to (w3)/2=r and then you can substitute that for r to solve for w.

Best ResponseYou've already chosen the best response.0I think it is easier if you solve for r and then solve for w. because you don't have to work with parentheses.
