Answer 3

Your welcome

Answer 4

4x - 2 = 18

So the opposite of subtraction is addition so you have to add 2 on both sides.

4x - 2 = 18

4x + 2 = + 2
4x _______ = ______

-2+2 is cancelled and add 18 +2 which equals 20. So your new equation would be:


4x = 20

Now you have to divide by 4.

4x = 20
_____ _____
4 4

Since 4x divide that by isn't a way to divide it is cancelled and now you have 20 divide it by 4.

which you answer will be 5.



Therefore, x=5.
