i just need to know hoe so that i can be able to finish my final exams

Hi Imari... just get x by itself, in two steps:

(1) Subtract 4 from 4-6x. And we have to also do that to the other side of the equation, to keep it balanced and both sides equal: 4-6x**-4** = 82**-4**;** ** now** **6x = 78

(2) Now we can divide both sides of the equation by 6, to get x by itself: 6x**/6** = 78**/6**; now** x = 13**
