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

(-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!
