Which of the following equation has the natural number as solution ?A)

1.	Which of the following equation has the natural number as solution ?A) 8x – 3 = 4 B) 2x = 1 C) 9x = 9 D) 3x + 1 = 0
Answer» Correct option is C) 9x = 9 Correct option is (C) 9x = 9 (A) 8x – 3 = 4 \(\Rightarrow\) 8x = 4+3 \(\Rightarrow\) x = \(\frac78\) is not a natural number. (B) 2x = 1 \(\Rightarrow\) x = \(\frac12\) which is not a natural number. (C) 9x = 9 \(\Rightarrow\) x = \(\frac99=1\) which is a natural number. (D) 3x + 1 = 0 \(\Rightarrow\) 3x = -1 \(\Rightarrow\) x = \(\frac{-1}3\) which is not a natural number.

Answer»

Correct option is C) 9x = 9

Correct option is (C) 9x = 9

(A) 8x – 3 = 4 \(\Rightarrow\) 8x = 4+3 \(\Rightarrow\) x = \(\frac78\) is not a natural number.

(B) 2x = 1 \(\Rightarrow\) x = \(\frac12\) which is not a natural number.

(D) 3x + 1 = 0 \(\Rightarrow\) 3x = -1 \(\Rightarrow\) x = \(\frac{-1}3\) which is not a natural number.
