Answer 1

6y - 4x = 5         (coloque na ordem)
4x + 2y = 1

-----------------------------
-4x + 6y = 5
 4x + 2y = 1
__________
         8y = 6
           y = 6/8
           y = 3/4
----------------------------------------
4x + 2y = 1
4x + 2. 3/4 = 1
4x + 6/4 = 1   (faz mmc)

16x + 6 = 4
_________
        4

16x + 6 = 4
16x = 4 - 6
16x = -2
    x = -2/16
    x = -1/8

V = {-1/8 ; 3/4}
