Answer:
1.) 6x - 4x - 16 = 14
6x - 4x = 14 + 16
2x = 30
x = 15
2.) 28 - 18y = -14y
-14y + 18y = 28
4y = 28
y = 7
4.) 1/2y - 6/5y = 3/4 + 1/4
5/10y - 12/10y = 4/4
-7/10y = 1
y = -10/7
5.) 2x + 8 = 7x -7
2x - 7x = -7 - 8
-5x = - 15
x = 5
I bet it's easier for you now to graph the solutions in a Cartesian plane. Just remember that the horizontal line on the plane is the y-axis, while the vertical line on a plane is the x - axis.
