Write two solutions of the form x = 0, y = a and x = b, y = 0 for the following equation :
5x – 2y = 10
उत्तर
Given that
5x – 2y = 10
Substituting x = 0 in the equation 5x – 2y = 10
We get 5 × 0 - 2y = 10
⇒ `y = - 10 /2 =-5`
Thus x = 0 and y = -5 is a solution of 5x - 2y = 10
Substituting y = 0 , we get
⇒ ` 5 x -2 xx 0 = 10 `
⇒ `5x = 10 `
⇒ `x = 2 `
Thus . x = 2 and y - 0 is a solution of 5x - 2y = 10
Thus . x = 0 . y = -5 and x = 2 .y = 0 are two solutions of 5x - 2y = 10
