Which is NOT true

9 + 4 = 17 - 4

8 + 7 = 14 + 3

11 = 19 - 8

5 + 8 = 20 - 7

1 answer

Let's evaluate each equation to find out which one is NOT true.

  1. 9 + 4 = 17 - 4

    • Left side: \(9 + 4 = 13\)
    • Right side: \(17 - 4 = 13\)
    • Both sides are equal, this equation is true.

  2. 8 + 7 = 14 + 3

    • Left side: \(8 + 7 = 15\)
    • Right side: \(14 + 3 = 17\)
    • The left side does not equal the right side, this equation is false.

  3. 11 = 19 - 8

    • Left side: \(11\)
    • Right side: \(19 - 8 = 11\)
    • Both sides are equal, this equation is true.

  4. 5 + 8 = 20 - 7

    • Left side: \(5 + 8 = 13\)
    • Right side: \(20 - 7 = 13\)
    • Both sides are equal, this equation is true.

The equation that is NOT true is 8 + 7 = 14 + 3.
