Question

How do you solve `21x + 798\leq 1281`?

Answer 1

`x <= 23`

Explanation:

Treat the inequality like an equation.

`21x +798 <= 1281`

First, subtract `798` from both sides of the equation:

`21x <= 483`

Then divide both sides of the equation by `21`

`x <= 23`

(If you multiply or divide by a negative number, then the inequality sign will change around.)
