What is the solution of this system of linear equations 3y=3/2x+6. 1/2y-1/4x=3

Which expression will have the same sum as 3_8 + 1/4?

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

Is this a polynomial function? i need to know asap
