Question

How do you solve `3m ≤ 9`?

Answer 1

`m <=3`

Explanation:

Given an inequality, the following operations can be performed on both sides of the inequality without effecting the orientation or validity of the inequality:

• Add or subtract the same amount to/from both sides;
• Multiply or divide by the same amount provided that amount is greater than 0 on both sides.

Therefore, given `3m <= 9`
we can divide both sides by `3` and the inequality remains valid:

`color(white)("XXXX")(3m)/3 <= 9/3`

`rarrcolor(white)("XX) m <= 3`
