Answer:

$\large \boxed{\sf \ \ x=0, \ \ y=-5 \ \ }$

Step-by-step explanation:

Hello, please consider the following.

We have two equations:

(1) -2x - 4y = 20

(2) -3x + 5y = -25

5*(1)+4*(2) gives

-10x - 20y -12x + 20y = 100 - 100 = 0

-22x = 0

x = 0

I replace in (1)

-4y = 20

y = -20/4 = -5

There is one solution x = 0, y = -5

Hope this helps.

Do not hesitate if you need further explanation.

Thank you

scoundrel [369]

$\huge\textsf{Hey there!}$

$\large\textsf{Formula:}$

$\mathsf{\dfrac{Sum\ of\ all\ terms}{Total\ number\ of\ values\ in\ the\ data}= your\ mean/average}$

$\mathsf{\dfrac{140+96+13}{3}}$

$\mathsf{140+36+13}$

$\mathsf{140 + 96 = \bf 236}$

$\mathsf{236 + 13}$

$\mathsf{ = \bf 249}$

$\mathsf{\dfrac{249}{3}}$

$\mathsf{= \bf 83}$

$\boxed{\boxed{\large\textsf{Possible answer: \huge \bf 83}}}\huge\checkmark$

$\large\textsf{Good luck on your assignment and enjoy your your day!}$
