Question

3x+5y=-40 and 2x-10y=15 then x-y is​

Answer 1

Answer:

–5

Step-by-step explanation:

By solving^^ equations 3x + 5y = -40 and 2x - 10y = 15, we get

$x = \frac{ - 65}{8}$

and

$y = \frac{ - 25}{8}$

Therefore, x - y will be equal to

$\frac{ - 65}{8} - \frac{ - 25}{8} \\ = \frac{ - 65 + 25}{8} \\ = \frac{ - 40}{8} \\ = - 5$

So our answer will be –5
