Question

3(-3-3x)=27 please answer fast

Answer 1

Answer:

x = -4

Step-by-step explanation:

Note the equal sign, what you do to one side, you do to the other. Do the opposite of PEMDAS.

PEMDAS =

First, divide 3 from both sides of the equation:

(3(-3 - 3x))/3 = (27)/3

-3x - 3 = 27/3

-3x - 3 = 9

Next, isolate the variable, x. Note that what you do to one side of the equation, you do to the other. Do the opposite of PEMDAS.

First, add 3 to both sides:

-3x - 3 (+3) = 9 (+3)

-3x = 9 + 3

-3x = 12

Next, divide -3 from both sides:

(-3x)/-3 = (12)/-3

x = 12/-3

x = -4

x = -4 is your answer.
