Okay -
So, the goal when we have an equation is to find the value of the variable. So, let's isolate that variable on one side of the equation!
* original equation
5x + 4 = 49.
* subtract four from both sides. if you do something on one side of the equation, you have to do it on the other.
5x + 4 - 4 = 49 - 4.
* now we are going to divide 5 on both sides to isolate x.
5x/5 = 45/5.
* and our answer is ...
x = 9. = )

You have to get x on its own.
5x=49-4
5x=45
45 divided by 5
Therefore x=9
