Question

How do you solve and graph the solution of `m-4<3`?

Answer 1

`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" >=)`.
