Answer:
Step-by-step explanation:
first step, cross multiply:
2(5x^2-3y^2) = 11xy.
second step, remove bracket:
10x^2-6y^2 = 11xy
third step, "follow the step"
10x^2 - 11xy -6y^2 = 0
fourth step, quadritic equation by middle term break:
10x^2 - 4xy - 15xy - 6y^2 =0
=>2x(5x-2y) - 3y(5x- 2y) =0
=>(2x-3Y)(5x-2y) = 0
therefore x = 3y/2 or 2y/5
you can find y in te same way
