PAIR OF LINEAR EQUATIONS IN TWO VARIABLES CHAPTER - 3 EXERCISE - 3.4

### QUESTION 1:-Solve the following pair of linear equations by the elimination method and the substitution method:(iv) x/2 + 2y/3 = -1 and x - y/3 = 3:

QUESTION 1:- Solve the following pair of linear equations by the elimination method and the substitution method: (iv) x/2 + 2y/3 = -1 and x - y/3 = 3

### QUESTION 2:-Form the pair of linear equations in the following problems, and find their solutions (if they exist) by the elimination method:(i) If we add 1 to the numerator and subtract 1 from the denominator, a fraction reduces to 1. It becomes ½ if we only add 1 to the denominator. What is the fraction?:
