Which is NOT true?5 + 14 = 20 - 19 + 5 = 7 + 715 = 4 + 1115 - 9 = 9 - 4

1 answer

Let's evaluate each of the equations to determine which one is NOT true:

  1. \( 5 + 14 = 19 \) (This is true)
  2. \( 20 - 19 = 1 \) (This is true)
  3. \( 5 = 7 + 7 \) (7 + 7 = 14, which is false)
  4. \( 15 = 4 + 11 \) (4 + 11 = 15, which is true)
  5. \( 15 - 9 = 6 \) (This is true)
  6. \( 9 - 4 = 5 \) (This is true)

So, the statement that is NOT true is:

\( 5 = 7 + 7 \).
