Question

solve for x and y √7x+√11y=77 and √3-√5y=15​

Answer 1

i think question is wrong because there is no x in the second part... so, plz check it...after then I will try to help u....

Answer 2

Step-by-step explanation:

i) Here a₁/a₂ = √7/√3 and b₁/b₂ = -√11/√5

==> The ratio of coefficients are not equal.

ii) Hence by the theory of system linear equations, they have unique solution. But here both the equations are equal to zero. So the system has trivial solution.

That is (x, y) = (0, 0)

iii) Also if you were to apply the substitution method and solving,

from the 2nd, x = (√5/√3)y.

Substituting this value of x in 1st, (√5/√3 + √11)y = 0; ==> y = 0; so x = 0
