Hi

solving the inequality:(Isolating x on one side of the Inequality)

 5 + 3x < 7

     3x < 2     |Subtracting 5 from each side of the Inequality

      x < 2/3   |Dividing each side of the Inquality by 3

Graphing on a number line would be an 'open' ended arrow extending to the left,

from the point 2/3.  (that is 2/3 not included due to the < sign)
