Solve the equation 3x3= -18 plz explain

Thats completely wrong, 3x3 = 9

The question is: 3x³ = -18

Isolate the x, do the opposite of PEMDAS

First, divide 3 from both sides

3x³/3 = -18/3

x³ = -18/3

x³ = -6

Next, cube root both sides to isolate the x
∛x³ = ∛-6

x = ∛-6

Simplify:

x =  -2

x = -2 is your answer

hope this helps
