2(6x - (5 - 6y + 5x) + 4y)

Step 1: Distribute the negative sign to the inside parenthesis - (5 - 6y + 5x) = -5 + 6y - 5x Step 2: Multiple 2 to the entire equation 2(6x -5 + 6y - 5x + 4y) = 12x - 10 + 12y - 10x + 8y Step 3: Simply the equation through adding and subtracting 12x - 10x = 2x - 10 12y + 8y = 20y Entire Simplified equation : 2x + 20y - 10

What is the cardinality of the set of odd positive integers less than 10?

Step 1: Let S = set of of positive integers less than 10 S = {1, 3, 5, 7, 9} 1, 3, 5, 7, 9 are all positive odd integers less than 10. Step 2: Count how many number are in the set. S = |S| which is 5 because there are 5 numbers in set S.
