A difference is the result of a subtraction.

Call the number n.

"seven times a number": 7n

"eight more than four times the number": 4n + 8

"The difference between seven times a number and eight more than four times the number": 7n - (4n + 8)

Answer: 7n - (4n + 8)

Isabella · Answer 2

Seven times a number = 7x

Eight more than four times the number = 8 + 4x

.

Suppose x = 5,

7x = 7*5 = 35 and

8 + 4x = 8 + 4*5 = 8 + 20 = 28
