Question

Twice the difference of a number and seven is equal to four less than the product of five and the number. What is the value of n?

Answer 1

-10/3 = n

Explanation:

let 'n' = number

2(n-7) = 5n-4

distribute the 2 to eliminate the parentheses:

2n - 14 = 5n - 4

subtract '2n' from each side to get:

-14 = 3n - 4

add 4 to each side to get:

-10 = 3n

-10/3 = n
