Solve 6x+57=2x+315 . A. x=−911 B. x=911 C. x=119 D. x=−119

Explanation:

Remember: we have to isolate the variable x, so that means we have to get x by itself.

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 x = 64.5
