In particular to the equations above, your goal is to find the value of x.
Step 1: isolate the variable (in this case,x).
Isolating the variable makes you narrow down what you are solving for.
Step 2: solve for the variable.
You can solve for the variable by making x alone (meaning with no coefficient).
If you have any questions on how you can do these while it still being mathematically legal, let me know and I will help.
