1. Direct solution. Solve the constraint equation for y. Substitute this into the second equation to get an equation only in x. Take the derivative, set it equal to zero, solve for x. Now back-substitute the value of x into the constraint equation and solve for y. 2. Lagrange multipliers. Check Wikipedia.
