Solve for
3x + 12= -12

x = -8

Step-by-step explanation:

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

First, subtract 12 from both sides:

3x + 12 (-12) = -12 (-12)

3x = -12 - 12

3x = -24

Next, divide 3 from both sides:

(3x)/3 = (-24)/3

x = -24/3

x = -8

x = -8 is your answer.

~

x = -8

Step-by-step explanation:

3x + 12= -12

3x = -24

x = -24/3

x = -8

the expected value of the random variable : 0, 1 and 2
