Answer:
So there are 8 red and 5 brown M&M
Step-by-step explanation:
Let X is red M&M
Let Y is brown M&M
We know that:
- 3 more red M&Ms than brown <=> X = Y +3
- A bowl contains 13 red and brown M&Ms <=> X + Y = 13
substitute X into the second equation: (Y + 3) + Y = 13
<=> 2Y = 10
<=> Y =5
=> X = 5 + 3 = 8
So there are 8 red and 5 brown M&M
