Which of the following is the correct way to represent the equation 3x

1.	Which of the following is the correct way to represent the equation 3x=9 in ax+by+c = 0 form?(a) 3x = -0y + 9(b) 3x + 0y = 9(c) 3x + 0y – 9 = 0(d) 3x + 0y = 9This question was posed to me during an online interview.My question is from Linear Equations in Two Variables topic in chapter Linear Equations in Two Variables of Mathematics – Class 9
Answer» The correct option is (c) 3X + 0y – 9 = 0 Explanation: In ax + by + c = 0, a, b and c are NUMBERS and a, b≠0 while X and y are variables. Given EQUATION is 3x=9. If we want it to REPRESENT in the ax+by+c=0 form, we can write 3x + 0y – 9 = 0 where a = 3, b = 0 and c = -9.
