Question

7-2x>4 (graph solution on nunber line)

Answer 1

Add 2x to both sides:

$7 > 2x+4$

Subtract 4 from both sides:

$2x < 3$

Divide both sides by 2:

$x < \dfrac{3}{2} = 1.5$

So, all numbers which are less than 1.5 are a solution for this inequality.

On a number line, you should highlight all numbers sitting at the left of 1.5 (1.5 excluded)
