Add 2x to both sides:
[tex] 7 > 2x+4 [/tex]
Subtract 4 from both sides:
[tex] 2x < 3 [/tex]
Divide both sides by 2:
[tex] x < \dfrac{3}{2} = 1.5 [/tex]
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)
