Write two solutions for each of the following equations:

(i) 3x+4y =7


(ii) x=6y


(iii) xy =4


(iv) x-y =4

(i) 3x + 4y = 7


At, x = 1


3 + 4y = 7


y = 1


Thus, x = 1, y = 1 is a solution


At, x = 0,


0 + 4y = 7


y = 7/4


Thus, x = 0, y = 7/4 is a solution.


(ii) x = 6y


At, y = 0


x = 0


Thus, x = 0, y = 0 is a solution.


At y = 1,


x = 6


Thus, x = 6, y = 1 is a solution


(iii) xy =4


At x = 0,


πy = 4


y = 4/π


Thus, x = 0, y = 4/π is a solution


At y = 0,


x + 0 = 4


x = 4


Thus, x = 4, y = 0 is a solution


(iv) x-y =4


At x = 0,


0 – y = 4


y = -4


Thus, x = 0, y = 4 is a solution


At x = 3,


2 – y = 4


y = -2


Thus, x = 3, y = -2 is a solution
