PAIR OF LINEAR EQUATIONS IN TWO VARIABLES: 

PAIR OF LINEAR EQUATIONS IN TWO VARIABLES CHAPTER - 3 EXERCISE - 3.3

QUESTION 1:-Solve the following pair of linear equations by the substitution method.(ii) s - t = 3 (iv) 0.2x + 0.3y = 1.3 s/3 + t/2 = 6 0.4x + 0.5y = 2.3: 

QUESTION 1:- Solve the following pair of linear equations by the substitution method. (ii) s - t = 3 (iv) 0.2x + 0.3y = 1.3 s/3 + t/2 = 6 0.4x + 0.5y = 2.3

(v) √2x + √3y = 0 (vi) 3x/2 – 5y/3 = -2 √3x - √8y = 0 x/3 + y/2 = 13/6: 

(v) √2x + √3y = 0 (vi) 3x/2 – 5y/3 = -2 √3x - √8y = 0 x/3 + y/2 = 13/6

QUESTION 2:-Solve 2x+3y = 11 and 2x - 4y = -24 and hence find the value of m for which y = mx + 3.: 

QUESTION 2:- Solve 2x+3y = 11 and 2x - 4y = -24 and hence find the value of m for which y = mx + 3.
