a) Two consecutive numbers whose sum is 29. Which of the following equations expresses that?

(a) \( X + X + 2 = 29 \)

(b) \( X + X + 1 = 29 \)

(c) \( X + X - 1 = 28 \)

(d) \( X + X + 1 = 30 \)

TRUE 😊

FALSE 😢

The correct answer is: (b) \( X + X + 1 = 29 \)

For consecutive numbers, if one is X, the next is X+1.

Their sum: \( X + (X + 1) = 29 \) which simplifies to \( 2X + 1 = 29 \)
