    There are five (5) brown M&Ms and Eight (8) red M&Ms.

    Step-by-step explanation:

    If the number of brown M&Ms = b

    If there are 3 more red M&Ms than brown, then the number of red M&Ms, r=b+3

    The total of Red and Brown M&Ms = 13

    r+b=13

    Since r=b-3

    b+3+b=13

    2b=13-3

    2b=10

    Divide both sides by 2

    b=5

    Number of red M&Ms

    r=b+3=5+3=8

    Therefore, there are 5 brown M&Ms and 8 red M&Ms.

    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
