Answer:
![x=3](https://tex.z-dn.net/?f=x%3D3)
Step-by-step explanation:
The first step is to isolate the variable on one side. In this case, let's try to bring x to the right. We do this by adding 3x to both sides, which gives us:
![7 = 2x + 1](https://tex.z-dn.net/?f=7%20%3D%202x%20%2B%201)
Now, to have just the x term on the right, we subtract one from both sides of the equation, giving:
![6 = 2x](https://tex.z-dn.net/?f=6%20%3D%202x)
The last step is to divide both sides by two to leave x by itself. Thus, after dividing, we get:
![3 = x](https://tex.z-dn.net/?f=3%20%3D%20x)
Hope this helps!
