Question

W/18=3 I don't understand

Answer 1

All you do is solve for W.
 you need to isolate the variable, and to do that you multiply by 18 on each side
 the /18 and the *18 will cancel each other out, leaving W by itself. Then 3*18 is equal to 54

W=54

Answer 2

If you want to solve for w:

w/18= 3
multiply both sides by 18

(w/18)(18)= (3)(18)
18 "cancels out" on the left side

w= 54


CHECK
54/18= 3
3= 3


ANSWER: w= 54

Hope this helps! :)
