Question

4x-5y=-2, 3x-y=-7 हो , तो ( x÷ y) का मान क्या होगा

Answer 1

Answer:

x = -3, y = -2

Step-by-step explanation:

Given equations are

4x-5y=-2  ...(i)

3x-y=-7    ...(ii)

Multiplying equation (i) with 1 and (ii) with 5

4x - 5y = -2

15x - 5y = 35  ...(iii)

Now subtracting (iii) from (i)

- 11x = 33

⇒ x = 33/ -11

⇒ x = -3

Now substituiting this value of x in equation (i)

⇒ 4(-3) - 5y = -2

⇒ - 12 - 5y = -2

⇒ - 5y = -2 + 12

⇒ - 5y = 10

⇒ y = 10/ - 5

⇒ y = -2

Therefore x = -3, y = -2
