2x-2 = 10 2x= 10+2 2x=12 x= 12/2 x=6
As written, that's 2(x - 6) You may have meant 4x^2 - 2x - 12 which would be 2(2x + 3)(x - 2)

2x+10=12 2x=2 x=1
5-4x=12-2x isolate your x's on one side 5=12-2x+4x 5-12=-2x+4x simplify -7=2x divide by 2 x=-7/2, or x=-3.5
2X divided by 4= 2X

If you mean 2x-3y=12 you... Solve for Y.Move the -3y over because it has the Y in it. -3y=2x+12Divide the other side by -3 (2 Divided by -3=0.6 but you will want -2/3)(12 Divided by -3=-4)Should look like this:Y=-2/3 - 4The Y Intercept=-4 and the Slope=-2/3 if your doing graphing.
2x-2 = 10 2x= 10+2 2x=12 x= 12/2 x=6

There is no solution to: 4(2x + 2) + 12 > 1004(2x + 2) + 12 > 100 For 4(2x + 2) + 12 > 1004(2x + 2) + 12 to have a solution x < -1 which makes 1004(2x + 2) + 12 < 12, BUT 1004(2x + 2) + 12 is supposed to be greater than 100. Perhaps there is a missing operator in the digits of 1004?
As written, that's 2(x - 6) You may have meant 4x^2 - 2x - 12 which would be 2(2x + 3)(x - 2)
2x + 12 = 2*x + 2*6 = 2*(x + 6)

4x + 12 = 2x - 2Subtract 2x from each side:2x + 12 = -2Subtract 12 from each side:2x = -14Divide each side by 2:x = -7
