# Math Help - inequalties

1. ## inequalties

1/4x - 1/2x>3
solve the inequality and sketch your solution on the number line. Use a test value to check your solution.

<---I---I---I---I---I---I---I---I--->

2. $\frac14x - \frac12x$>3

$x(\frac14 - \frac12)$>3

$x(\frac14 - \frac24)$>3

$x(-\frac14)$>3

-3> $x(\frac14)$

$-3*4$ > x

x < -12

So on your number line, just find -12, then draw an arrow from -12 all the way down towards the left.

To test a value of x, you may choose any x less than -12, so try -15. When you plug it into $\frac14x - \frac12x$>3, you should get a number >3.
