I'm going to presume that you made a typo and that you really mean:





because the way you wrote it, since and are NOT the same thing, you have an underdetermined system of two equations in three variables.

Solve the first equation for in terms of everything else.



Do the same thing for the second equation



Now that you have two things equal to set them equal to each other:



Put the quadratic into standard form and solve for . Then use the value of to calculate by substituting back into one of the original equations.
