> 21
what you have to do is get the x to be on its own. So we need to get rid of the 4. Since it's a fraction and fractions are division, you need to multiply both sides by 4. The reason as to why you multiply is because multiplication is the opposite if division. By multiplying both sides you get rid of the four and you are left with:
