Question

Nine less than two times a number is five more than this number. What is the number?

Answer 1

14

Explanation:

let n be the number then 2 times the number is 2n and so

2n - 9 = n + 5 ( subtract n from both sides )

n - 9 = 5 ( add 9 to both sides )

n = 14

then the required number is 14
