maks197457 [2]

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
