Can someone help me with this I’m stuck please

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

Solve x+3y=6 and 4x-6y=6 by elimination . show work !

If you could answer these your a life saver
