2x+14y=-8. solve for y. show work

7x+14y=14. solve for y. show your work

10x+2y=20. solve for y. show your work

2x + 14y = - 8

2x + 14 (0) = - 8

2x + 0 = 8

2x = 8

x = 4

(x, y) = (4, 0)

7x + 14y = 14

7x + 14 (0) = 14

7x + 0 = 14

7x = 14

x = 2

(x, y) = (2, 0)

10x + 2y = 20

10x + 2 (0) = 20

10x + 0 = 20

10x = 20

x = 2

(x, y) = (2, 0)

Y=0

2x+14y=-8 ... x=-4

7x+14y=14 ... x=2

10x+2y=20 ... x=2
