    The expression for the total number of coins owned by both Nancy and Kelvin is

    = x + 2x - 4

    = 3x - 4

    Step-by-step explanation:

    The relationship between the number of coins collected by each person is given in the statement "Nancy has x coins. Kevin has 4 coins fewer than two times the number of coins Nancy has."

    Number of Nancy's coins = x

    Since Kevin has 4 coins fewer than two times the number of coins Nancy has

    Number of Kelvin's coins = 2x - 4 = 2 (x-2)

    Hence the expression for the total number of coins Nancy and Kelvin have

    =x + 2x - 4

    = 3x - 4
