Question

The solution for the pair of linear equations in two variables root5 ×+ root 7y=0and root 7×- root5 y=0 is

Answer 1

Answer:-

By substitution method,

√5x +√7y=0

x= -√7y/√5........ equation 1

√7x-√5y=0

substituting value of x from equation 1

√7(-√7y/√5) -√5y=0

-7y/√5 -√5y =0

-7y-5y/√5=0

-12y/√5=0

y= 0

substituting value of y in equation 1

x= -√7(0)/√5

x=0

Therefore solution for the pair of linear equation is x=0 and y=0
