Best ResponseYou've already chosen the best response.0no, I mean that you have two unknowns and one equation, so you can't get a number answer so do you want it solved for a or b ?

Best ResponseYou've already chosen the best response.0that changes things... you need as many equations as unknowns to solve a problem, so the other equation is essential ab=6 a=2b+7 substitute the second expression for 'a' into the first equation: 2b+7b=6 this can be solved for b once you have the value of b plug that number into the second equation, which gives you the value of a.
