# Write two solutions for each of the following equations:(i) 3x+4y =7(ii) x=6y(iii) x+πy =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
