The system of equations may be solved by hand calculation or by using the crossing-graphs method. Solve the following system using the crossing-graphs method. x + y = 1 4x + 5y = 0 (x, y) Need Help? Read It [-/2 Points] DETAILS (x, y) = CRAUDCOLALG6 3.5.SB.025. MY NOTE This exercise involves a system of equations that is not easily solved by hand calculation. Solve the following system using the crossing-graphs method. (Round your answers to two decimal places.) 2.2x + 3.7y = -1.48 2.5x 1.6y = 3.78
