Pls help me with an easy question in #7 in the screen shot

When the solutions to each of the two equations below are graphed in the xy-coordinate plane, the graphs of the solutions intersect at two places. write the y-cordninates of the points of intersection in the boxes below in order from smallest to largest. y=2x y=x^2-3

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