<span>solve -2(2x + 5) - 3 = -3(x - 1)
-4x - 10 -3 = -3x + 3
-4x - 13 = -3x + 3
Add 3x to both sides
-4x - 13 +3x = -3x +3
Simplify
-x - 13 = 3
Add 13 to both sides
-x - 13 + 13 = 3 + 13
Simplify
-x = 16
multiply both sides by (-1)
x = -16</span>

Step-by-step explanation:
P is the independent variable and b is the dependent variable
Problem 3
Disjoint events are two (or more) events that cannot happen at the same time. An example would be flipping heads and tails at the same time with the same coin. Another example is selecting an ace of spades and selecting an ace of diamonds, when you only select one card.
In general notation, P(A and B) = 0 if and only if A and B are disjoint.
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 0.3 + 0.1 - 0
<h3>P(A or B) = 0.4</h3>
=========================================
Problem 5
Same idea, but different numbers
P(A or B) = P(A) + P(B) - P(A and B)
P(A or B) = 1/3 + 1/4 - 0
P(A or B) = 4/12 + 3/12 - 0
<h3>P(A or B) = 7/12</h3>
