Technically speaking, you can't solve that system. That is because you have two equations and three variables,

,

, and

. Yes,

is different than

.

Now on the off chance that you made a typo and you really meant:

and

you have two equations where

all by itself is equal to some expression in

. Set the two expressions in

equal to each other:

And solve for

Finally substitute the value you discover for

back into either of the original equations and calculate
