Question

2x - y = 3
x = -2y - 1

Answer 1

Answer:

          x  = 1,  y = - 1

Step-by-step explanation:

2x - y = 3

x = -2y - 1

2x - y = 3

2(-2y - 1) - y = 3

-4y - 2 - y = 3         {add 2 to both sides}

- 5y = 5             {divide both sides by (-5)}

 y = -1

x = -2y - 1 = -2(-1) - 1 = 2 - 1 = 1
