If you get an answer using a different method do you still get the marks?

If you get an answer using a different method do you still get the marks in the junior cert? for example question - solve the following inequality and show on a number line 3x-4 > 5 , x E R they do it like this - 3x-4 > 5 3x > 5 + 4 3x > 9 x > 3, x E R final answer 3 (From my maths book) But I do it like this. 3(1) - 4 > 5 3 + 1 = 4 4 + 4 = 8 8 - 5 = 3 Final Answer 3? Will I get any marks for doing it that way?! just wondering. or should I learn how to do it the way the book did it? sorry for the long question
