Question

How do i solve 7x^{2} +11y^{2} =40

Answer 1

Explanation:

There is no solution as you have two variables and only one equation. The best you can do is solve for one variable as a function of the other.

`7x^2+11y^2=40\\ \\ 11y^2=40-7x^2\\ \\ y^2=(40-7x^2)/(11)\\ \\ y=\sqrt{(40-7x^2)/(11)}`
