What is x in the equation -4x < 84

Sagot :

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.
