Step 1:
Let’s look at our equation:
Let’s subtract 2x from both sides of the equation, since our goal is to isolate the variable. You could also subtract 6x from both sides, but you would end up with a negative number, and I find it easier to deal with positive numbers.
Step 2:
Now, let’s subtract 57 from both sides of our equation.
Step 3:
Since we have to isolate x, let’s divide both sides of the equation by 4.
Our final answer: x = 64.5
