Two step equations example
2x + 2 = 10
Inverse operation. What is the opposite of +2?
-2 is!
Apply that to both sides to balance it
2x + 2 = 10
- 2 -2
2x = 8
2x/2 = 8
We divided because it is the opposite of multiplication.
2x/2 = 8/2
x = 4
Answer: x = 4
We're given the following probabilities:





(a) Yes,
and
are mutually exclusive. This is exactly what zero probability of their intersection means. The two events cannot occur simultaneously.
(b) Use the definition of conditional probability to expand:


(c) By the law of total probability,

(d) Bayes' theorem says

Hi!
Whatever we do to the inequality, we have to do it to both sides.
Subtract 14 from both sides
14 - 14 - 3x < -1 - 14
-3x < -15
Divide by -3 on both sides
-3x/-3 < -15/-3
x < 5
Because we divided by a negative number, the equality sign flips.
x > 5
^ the answer
Hope this helps! :)
