Answer:
the value of x and y is zero
given:- equations √2x+ √3y=0 and √3y-√7y=0
to find :- solve the questions
Step-by-step explanation:
solution:- root 2 x + root 3 y is equal to zero ...(1)
root 3 x minus root 7 y is equal to zero...(2)
multiple (1) by root 3 and (2) by root 2.
root 6 x + root 9 y is equal to zero...(3)
root 6x .... root 16 y is equal to zero....(4)
subtracting (4) from (3)
root 9y + root 16 y is equal to zero
y is equal to zero
from (1)
root 2 x + root 3 (0)=0
root 2 x is equal to zero
x is equal to zero
x is equal to zero, y is equal to zero (answer)
