Question

If -14/63=x/9=-18/y ,then (x,y) is

Answer 1

$\huge\red {\underline {\mathbb{answer}}}$

$\frac{ - 14}{63} = \frac{x}{9} = - \frac{18}{y}$

$\frac{ - 14}{63} = \frac{x}{9}$

$- 14 \times 9 = x \times 63$

$- 126 = 63x$

$x = \frac{ - 126}{63}$

$x = - 2$

$\frac{ - 14}{63} = \frac{ - 18}{y}$

$y \times - 14 = - 18 \times 63$

$- 14y = - 1134$

$y = \frac{ - 1134}{ - 14}$

$y = 81$

(x,y)=(-2,81)
