Question

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

Answer 1

(-9, -3)

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!!!!
