5x - 7 < 28

Add '7' to both sides

5x < 35

Divide both sides by '5'

x < 7

verification

When x = 6

5(6) - 7 = 30 - 7 = 23 < 35

Rules for 'Inequalities'.

1. Treat it as an 'equals (=)'.

2. Only change the direction of the 'Inequaity' when dividing by a negative number or a fraction.

Hope that helps!!!!
