4+6x>4x-18

Solve this like you would solve the problem if there were an equal sign in the problem. Put your "Xs" on one side of the equation and your numbers on the other side......

4 + 6x > 4x - 18 (original equation)
4 + 6x - 4x > 18 (subtract 4x from both sides of the equation)
4 + 2x > 18 (6x - 4x = 2x)
2x > 18 - 4 (subtract 4 from both sides of the equation)
2x > 14 (18 - 4 = 14)
x > 7 (divide both sides by 2 to isolate the 'x')

If you graph this, you draw a number line with a circle around the 7 (you don't fill in the circle) and thennnn you draw an arrow from that circle that goes to the right.

I hope this is helpful. :-)

I think the original solver got this one wrong when they dropped a minus sign.
Let's try it again and keep track of the signs:

4 + 6x > 4x - 18
4 + 6x - 4x > 4x - 4x - 18
4 + 2x > -18
4 - 4 + 2x > -18 - 4
2x > -22
x > -11
