Question

Determine whether the inequality is always, sometimes, or never true.

Answer 1

Treat this as an ordinary linear equation. Try to isolate x, as some value. Also remember the basic rules of inequalities: If you're dividing, or multiplying, by a negative, you flip the inequality.

Answer 2

You get −4x−18>−4x+9 now you can add 4x to both sides, which means all the x's are gone, and you get −18>9
