समीकरण हल कीजिए


$4x - 5 + 16 = 0 \\ 2x + y - 6 = 0$
​

Answer 1

Answer:

multiplying equation 2 by 2

(2x + y - 6 = 0) × 2

4x + 2y - 12 = 0

4x - 5y + 16 = 0

__________________

7y - 28 = 0

7y = 28

y = 4

substitute y value in eqn 1

4x - 5y + 16 = 0

4x - 5(4) + 16 = 0

4x - 20 + 16 = 0

4x - 4 = 0

4x = 4

x = 1
