Answer:
![x=-5](https://tex.z-dn.net/?f=x%3D-5)
Step-by-step explanation:
Combine all like terms using addition and subtraction as necessary. Make sure to keep the symbol in front of any term when rearranging (ie. -4):
![(7-4)+(6x+2x)=-37\\\\3+8x=-37](https://tex.z-dn.net/?f=%287-4%29%2B%286x%2B2x%29%3D-37%5C%5C%5C%5C3%2B8x%3D-37)
Use inverse operations to isolate the variable. Subtract 3 from both sides, the 3 will cancel out:
![3-3+8x=-37-3\\\\8x=-40](https://tex.z-dn.net/?f=3-3%2B8x%3D-37-3%5C%5C%5C%5C8x%3D-40)
Use inverse operations to isolate x. Divide both sides by 8, the 8 will cancel out:
![\frac{8x}{8} =\frac{-40}{8} \\\\x=-5](https://tex.z-dn.net/?f=%5Cfrac%7B8x%7D%7B8%7D%20%3D%5Cfrac%7B-40%7D%7B8%7D%20%5C%5C%5C%5Cx%3D-5)
The value of x for the given equation is -5.
