A marble is drawn randomly from a jar that contains 5 purple marbles, 2 blue balls, and 3 pink marbles. Find the probability of randomly selecting

You have a 50% chance of getting a purple marble, a 30% chance for a pink one, and a 20% chance of getting a blue marble.

a and c

for infinitely many solutions we require both left and right sides to be equal

distribute and simplify

a

14 - 8x = 20 - 8x - 6 = 14 - 8x ← both sides equal so infinite solutions

b

6x - 54 = 6x - 54 + x = 7x - 54 ← not equal

c

4x + 16 = 4x + 10 + 6 = 4x + 16 ← both sides equal so infinite solutions

d

5x - 40 + 10 = 5x + 10

5x - 30 = 5x + 10 ← not equal
