which linear system has been correctly solved for one of the variables from the following system? 2x - y = -1 2x y = -7 2x - y =

-1 y = 2x - 7 2x - y = -1 y = -2x 7 y = 2x 1 2x y = -7 y = -2x 7 2x y = -7

If you would like to solve the system of linear equations, you can do this using the following steps:

2x - y = -1 ... y = 2x + 1
2x + y = -7 ... y = -7 - 2x

The correct result would be: y = 2x + 1, <span>2x + y = -7.</span>
