2x + 12 = 4x + 4
i need you to solve for x

The answer is 8

Step-by-step explanation:

Simplifying

2x + 12 = 4x + -4

Reorder the terms:

12 + 2x = 4x + -4

Reorder the terms:

12 + 2x = -4 + 4x

Solving

12 + 2x = -4 + 4x

Solving for variable 'x'.

Move all terms containing x to the left, all other terms to the right.

Add '-4x' to each side of the equation.

12 + 2x + -4x = -4 + 4x + -4x

Combine like terms: 2x + -4x = -2x

12 + -2x = -4 + 4x + -4x

Combine like terms: 4x + -4x = 0

12 + -2x = -4 + 0

12 + -2x = -4

Add '-12' to each side of the equation.

12 + -12 + -2x = -4 + -12

Combine like terms: 12 + -12 = 0

0 + -2x = -4 + -12

-2x = -4 + -12

Combine like terms: -4 + -12 = -16

-2x = -16

Divide each side by '-2'.

x = 8

Simplifying

x = 8

you should at least use a calculater

step-by-step explanation:

answer: expected value of x = 1.0

step-by-step explanation:

p(x=0) = 0.25

p(x=1) = 0.50

p(x=2) = 0.25

expected value for x = 0×0.25 + 1×0.5 + 2×0.25 = 1.0
