For eg: elimination

Answer 1

Dear Student,
​​​​​​For mathematical problems you must develop a skill to identify or guess the most probable answer by doing a lot of problems. And thus you can back substitute the guessed answer and check if the answer is correct or not. The only thing you have to do is practice.

Good Luck!!
