Answer 2

Answer:

$\underline{\bold {x = \frac{7}{5} \\,y = \frac{2}{5} }}$

Step-by-step explanation:

$\frac{x}{-20-(-27)} = \frac{y}{-18 -(-20)} = \frac{1}{15-10} \\\implies \frac{x}{7} = \frac{y}{2} = \frac{1}{5} \\\\\frac{x}{7} = \frac{1}{5} \\\implies 5x = 7\\\implies \bold{x = \frac{7}{5}}\\\\\frac{y}{2} = \frac{1}{5} \\\implies 5y = 2\\\implies \bold{y= \frac{2}{5}}$
