Solve this system of linear equations. sperate the x- and y- values with a comma. 2x = -78 - 20y and -x = -51 -20y

Step-by-step explanation:

Are you looking for point form or equation form?

(-9, -3)

Step-by-step explanation:

Isolate the variables to one side:

2x + 20y = -78

-x + 20y = -51

Subtract the equations:

3x = -27

Divide:

x = -9

Plug it back in:

9 = -51 - 20y

Solve:

60 = -20y

y = -3

Check:

-18 = -78 - (-60)

-18 = -18

YAY YOU'RE DONE

in the attachment.   i didn't see your choices.   the word which means there is choices.

step-by-step explanation:

(x,y)

x tells you how much left or right you go from the origin

y tells you how much down or up you go from the origin

so for example (-3,2), you go left 3 and up twice. i denoted which of the ordered pairs is which in my graph.
