Nancy and Kevin collect coins. Nancy has x coins. Kevin has 4 coins fewer than two times the number of coins Nancy has. Write and simplify an expression for the total number of coins Nancy and Kevin have.

total: 3x + 4

Step-by-step explanation:

Nancy = x

Kevin = 2x+4

together = 3x + 4

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
