Question 1014950: Which linear system has been correctly solved for one of the variables from the following system?:

2x - y = -1
2x + y = -7
a. 2x - y = -1 y = 2x - 7
b. 2x - y = -1 y = -2x + 7
c. y = 2x + 1 2x + y = -7
d. y = -2x + 7 2x + y = -7

You can put this solution on YOUR website!
the answer is c
:
since solving the first equation for y, you get y = 2x + 1
