28y - 16y = 12y.
-3x+16y = 28 3(x-3y = 7) Multiply the bottom equation by 3 then add both equations together in order to eliminate x: 7y = 49 y = 7 Substitute the value of y into the original to find the value of x: So: x = 28 and y = 7
The equation does not represent that of a parabola.

5(4x-3y = 11) 4(5x+4y = 6) Multiply the top equation by 5 and the bottom by 4: 20x-15y = 55 20x+16y = 24 Subtract: -31y = 31 y = -1 Substitute the value of y into the original equations to find the value of x: So: x = 2 and y -1
