Question

root 7x- root 3y=0 and root 5x+root 2y=0​

Answer 1

√7x-√3y=0........(1)

√5x+√2y=0.......(2)

Taking square on both side of (1) and (2) both

7x-3y=0.......(3)

5x+2y=0...…(4)

Multiplying equation (3) by 2 and (4) by 3

14x-6y=0……(5)

15x+6y=0……(6)

Adding equation (5) and (6)

14x-6y=0

15x+6y=0

29x=0

x=0÷29

x=0

substituting the value of x in equation (5)

14x-6y=0

14×0-6y=0

0-6y=0

-6y=0

-y=0÷6

-y=0

i.e.y=0

0 cannot be negative.
