Question

Write the solution using interval notation
-4x>4

Answer 1

-4x > 4

Divide both sides by -4.

***When dividing or multiplying an inequality by a negative number, reverse the inequality sign.**:

(-4x) / -4 < 4 / -4

Simplify:

x < -1

Change to interval notation (the solution set is all x-values less than -1):

(-∞, -1)
