Question

2/x-3/y+5=0 3/x+2*y+4=0 find x and y
​

Answer 1

Answer:

When x = 0, 2(0) + y = 7

      ⇒                      0 + y = 7

      ⇒                      y =7

      ∴ Solution is (0, 7).

      When x = 1, 2(1) + y = 7

      ⇒                      y = 7 – 2

      ⇒                      y = 5

      ∴ Solution is (1, 5).

      When x = 2, 2(2) + y = 7

      ⇒                      y = 7 – 4

      ⇒                      y = 3

      ∴ Solution is (2, 3).

      When x = 3, 2(3) + y = 7

      ⇒                      y = 7 – 6

      ⇒                      y = 1

      ∴ Solution is (3, 1).
