Answer:
x = 16.5
Step-by-step explanation:
In this equation, we're trying to figure out the value of x, or what it's equivalent to in this particular situation. Let's look at what we have right now:
12.7 = x - 3.8
How can we get x by itself? Well, the thing that immediately comes to my mind is <em>adding 3.8 to both sides</em>. This will isolate x and help is figure out what it's equal to. So, we start out with:
12.7 = x - 3.8
...and then we add 3.8 to both sides to get:
16.5 = x
And that's the value of x. We can check our answer by replacing x with 16.5 and seeing if both sides of the equation are equivalent:
12.7 = 16.5 - 3.8?
12.7 = 12.7
So, we're correct. If you need any more help, let me know! :)
