Answer:
![x=160](https://tex.z-dn.net/?f=x%3D160)
Step-by-step explanation:
![\frac{x}{6+4} =16](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B6%2B4%7D%20%3D16)
![\frac{x}{10} =16](https://tex.z-dn.net/?f=%5Cfrac%7Bx%7D%7B10%7D%20%3D16)
![x=16 \times 10](https://tex.z-dn.net/?f=x%3D16%20%5Ctimes%2010)
![x=160](https://tex.z-dn.net/?f=x%3D160)
Answer:
D
Step-by-step explanation:
Consider the equation:
![\dfrac{3}{4}(24-16x)=-\dfrac{2}{3}(18x-27)](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B4%7D%2824-16x%29%3D-%5Cdfrac%7B2%7D%7B3%7D%2818x-27%29)
Use distributive property in both sides:
![\dfrac{3}{4}\cdot 24-\dfrac{3}{4}\cdot 16x=-\dfrac{2}{3}\cdot 18x+\dfrac{2}{3}\cdot 27\\ \\3\cdot 6-3\cdot 4x=-2\cdot 6x+2\cdot 9\\ \\18-12x=-12x+18](https://tex.z-dn.net/?f=%5Cdfrac%7B3%7D%7B4%7D%5Ccdot%2024-%5Cdfrac%7B3%7D%7B4%7D%5Ccdot%2016x%3D-%5Cdfrac%7B2%7D%7B3%7D%5Ccdot%2018x%2B%5Cdfrac%7B2%7D%7B3%7D%5Ccdot%2027%5C%5C%20%5C%5C3%5Ccdot%206-3%5Ccdot%204x%3D-2%5Ccdot%206x%2B2%5Ccdot%209%5C%5C%20%5C%5C18-12x%3D-12x%2B18)
Separate terms with x into the left part and terms without x into the right part:
![-12x+12x=18-18\\ \\0=0](https://tex.z-dn.net/?f=-12x%2B12x%3D18-18%5C%5C%20%5C%5C0%3D0)
Since you get true equality 0 = 0, the equation is true for all real values of x. So, the equation has infinitely many solutions.
