You might be thinking i would say ....

you dont even know the answer to such an easy problem. What do you learn at school? Don't you have a book or any mind to see if anyone answered such questions in past already ! Do you do anything on yourself or not or just come here for help!?

but now is oil by say all that cuz it's MEAN ! And I'm here to help u!

So we'll do this like

5x-x+4=28

first we shall subtract x from 5x

4x +4=28

now we will take 4 to the other side and subtract from 28.

4x= 28 -4

4x = 24

now take 4 to the other side and divide by 24 and yay u got the answer!

x = 24/4

x= 6 ANSWER!
