Marble Count After Giving Away Blue Marbles

Medium Patterns And Algebra Basic Equations

Alice has a collection of colored marbles. She has red, blue, and green marbles in the following quantities:

- Red marbles: 12

- Blue marbles: 8

- Green marbles: 5

If Alice gives away a total of $x$ marbles, where $x$ is the number of blue marbles she has, how many marbles will she have left?

Which equation represents the number of marbles Alice has after giving away the blue marbles?

$12 + 8 + 5 - x = 25 - x$

$12 + 8 + 5 - x = 25 - 8$

$12 + 8 + 5 - x = 12 + 8 + 5 - 8$

$12 + 8 + 5 - x = 5$
