16x - 16 = 4 (?)

What is x?

1.25

Step-by-step explanation:

You want the numbers to be on one side and the x to be on the other side.

To do this, you will add 16 to 4, this wll be 20

Now you have 16x=20, all you have to do is divide by x to get your number

so 20 divide by 16 is 1,25

1,25 is x
