#m < 7#

Explanation:

Solving an inequality is very similar to solving an equation. You use the same type of operations. The exception is when you divide by #-1#, this causes the inequality to be reversed.

Given: #m - 4 < 3#

Add #4# to both sides of the inequality: #m - 4 + 4 < 3 + 4#

Simplify: #m < 7#

Inequalities can be graphed on a number line. An open hole or "(" means the number is not included ( < or > ). A solid dot or a "]" means the number is included #(<= "or" >=)#.
