1. Remember 1. find your variable.
2. Identify what is happening to that side of the equation.
3. Do the opposite operation to isolate your variable (get it by itself); so if you have a x + 3. Than you need to subtract 3 on both sides.
This is key. To balance your equation and find out what the unknown variable is, you have to do the opposite on both sides.
For instance, if you have a var. with a co-efficient of 3 multiplying times 3: 3x, you will need to divide by 3 to get x by itself Sometimes you have a couple of steps, just take time and balance and isolate that one side of the equation.
Good luck and bring your questions to me in the morning.
