A secret number is added to 6. The total is multiplied by 5 to get 50. What is the secret number?

Take this algebraic expression in pieces:
  • Let the secret number be n.
  • Added to means we add 6 to n: n + 6
  • The total is multiplied by 5: 5(n + 6)
  • The phrase to get means equal to, so we set 5(n + 6) equal to 50
5(n + 6) = 50

To solve this equation for n, we type it in our search engine and we get:
n = 4
