Solve the following system of equations. 3x + 3y = 123 5x2-4y = -20 Solution(s): Enter your answers as points: (x, y) Because these systems are non-linear, you may have more than one solution. . If you have more than one solution, enter your answers as a list of points: (0, 30), (x1,y1) Use 'sqrt(...)' to enter radical answers, do not use decimal approximations.
