Answer:
x > -21
Step-by-step explanation:
To solve for x, isolate it. So, divide both sides by -4. However, remember that when dealing with inequalities, flip the sign in the middle when dividing or multiplying by a negative number.
[tex]-4x<84\\\frac{-4x}{-4} <\frac{84}{-4} \\x>-21[/tex]
So, x > -21.
