Answer: ![x=4](https://tex.z-dn.net/?f=x%3D4)
Step-by-step explanation:
Group like terms:
![\left(2x+x\right)-7=5](https://tex.z-dn.net/?f=%5Cleft%282x%2Bx%5Cright%29-7%3D5)
Simplify the arithmetic:
![3x-7=5](https://tex.z-dn.net/?f=3x-7%3D5)
Add 7 to both sides:
![3x-7+7=5+7](https://tex.z-dn.net/?f=3x-7%2B7%3D5%2B7)
Simplify the arithmetic:
![3x=5+7](https://tex.z-dn.net/?f=3x%3D5%2B7)
Simplify the arithmetic:
![3x=12](https://tex.z-dn.net/?f=3x%3D12)
Divide both sides by 3:
![\frac{3x}{3}=\frac{12}{3}](https://tex.z-dn.net/?f=%5Cfrac%7B3x%7D%7B3%7D%3D%5Cfrac%7B12%7D%7B3%7D)
Simplify the fraction:
![x=\frac{12}{3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B12%7D%7B3%7D)
Find the greatest common factor of the numerator and denominator:
![x=\frac{4\cdot 3}{1\cdot 3}](https://tex.z-dn.net/?f=x%3D%5Cfrac%7B4%5Ccdot%203%7D%7B1%5Ccdot%203%7D)
Factor out and cancel the greatest common factor and the answer will be:
![x=4](https://tex.z-dn.net/?f=x%3D4)
