Question

What will be the solution of x - 2y = 0 and 3x + 4y = 20 from the given figure? (A) P (0,5) (b) A (0,0) (c) B (2,1) (d) Q (4.2)​

Answer 1

Answer:

tum hoo briliant tum too mhan hoo

Answer 2

x-2y =0

so , x = 2y

now put x=2y in

3x +4y = 20

3(2y) + 4y = 20

6y + 4y = 20

10y = 20

y = 2

so , x = 4

so the correct option is point Q ( 4,2 )
