There are red and blue marbles in a jar. There are 2 more red marbles than blue. There are 8 marbles in all. How many red marbles? How many blue marbles?
Would it be 6 red marbles 2 blue marbles.
x + x + 2 = 8
2x = 6
x = 3
3 blue marbles and 5 red marbles
To solve this problem, let's break it down step by step.
Let's say there are x blue marbles in the jar. Since there are 2 more red marbles than blue marbles, there must be x + 2 red marbles.
The total number of marbles is given as 8. Therefore, we can write an equation to represent this: x + (x + 2) = 8.
Simplifying the equation, we have: 2x + 2 = 8.
Subtracting 2 from both sides, we get: 2x = 6.
Dividing both sides by 2, we find: x = 3.
So, there are 3 blue marbles in the jar. Since there are 2 more red marbles, there must be 3 + 2 = 5 red marbles.
Therefore, there are 5 red marbles and 3 blue marbles in the jar.
