If you multiply the first equation by 6, you will get: 12x + 18y = 48 No way are the x terms going to add out when the second equation x term is -6x 12x - 6x do not add to 0.

2x + 3y = 8 --Multiply by 3 -- 6x + 9y = 24 -6x + 4y = 11 -6x + 4y =11 --------------------------------------------- 13y = 35 The x terms added out.
