Pls help I need a good grade

The linear combination method is applied to a system of equations as shown. 4(.25x + .5y = 3.75) → x + 2y = 15 (4x – 8y = 12) → x – 2y = 3 2x = 18 what is the solution of the system of equations? (1,2) (3,9) (5,5) (9,3)

Which steps could be part of the process in algebraically solving the system of equations, y+5x=x^2+10 and y=4x-10
