x=15 and y=-10

is the correct answer.

Answer 2

Answer:

x=15 or -10

Step-by-step explanation:

$\frac{ {x}^{2} }{15} - \frac{x}{3} - 10 = 0 \\ \frac{ {x}^{2} - 5x - 150 }{15} = 0 \\ {x}^{2} - 5x - 150 = 0 \\ {x}^{2} - 15x + 10x - 150 = 0 \\ x(x - 15) + 10(x - 15) = 0 \\ (x - 15)(x + 10) = 0$

x-15=0 , x+10=0

x=15 , x=-10
