(a) -6x- y = 3

$6x + y = -3\\ y = -6x -3$

(b) 3x-4y =12

$3x - 4y = 12\\-4y = -3x +12\\4y = 3x -12\\\\y = \frac{3}{4}x -3$

(c)-2x + 5y = 10

$-2x + 5y = 10\\5y = 2x + 10\\y = \frac{2}{5}x + 2$

(d) x + 2y = 4

$x+2y=4\\2y = -x + 4\\y = \frac{-1}{2} x +2$

(e) 8x- 4y = 3

$8x - 4y =3\\-4y = -8x + 3\\4y = 8x -3\\y = 2x -\frac{3}{4}$

(f) 4x + 5y = -6

$4x + 5y = -6\\5y = -4x - 6\\y = \frac{-4}{5} x -\frac{6}{5}$
