प्रश्न 5 समीकरण हल कीजिए- (आलेख विधि से नही)
4x -5y+16 = 0
2x+y-6 = 0​

Answer 1

Step-by-step explanation:

-1xy = -16

xy = -16 +1

xy = -15 ANS

2x+y =6

3xy = 6

xy = 6-3

xy = 3 ANS

Answer 2

Step-by-step explanation:

here,

4x-5y+16=0. eq(1)

4x-5y=-16

-y=-16-4x/5

-y=-20/5

-y=-4

hence,

y=4

then,

putting 4 in eq.1

so,

4x-5×4=-16

so,

x=-16/-20×1/4

x =1/5
