Question 451 Mark
Directions: In the following questions, the Assertions (A) and Reason(s) (R) have been put forward. Read both the statements carefully and choose the correct alternative from the following:
Assertion: Getting a solution is to take x = 0 and get thecorresponding value of y. Similarly, we can put y = 0 and obtain the corresponding value of x.
Reason: 4x + 3y = 12 Taking x = 0, we get 3y = 12, i.e., y = 4. So, (0, 4) is a solution of the given equation. Similarly, by taking y = 0, we get x = 3. Thus, (3, 0) is also a solution.
