7 times a number increased by 4 times the number

Let a number and the number be an arbitrary variable. Let's call it x. We have an algebraic expression. Let's take it in pieces:

  • 7 times a number: 7x
  • 4 times the number: 4x
  • The phrase increased by means we add 4x to 7x:
  • 7x + 4x
  • Simplifying, we get: (7 + 4)x
  • 11x
