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
