Answer:
![5](https://tex.z-dn.net/?f=5)
Step-by-step explanation:
Let the number be
.
![3x+6=5x-4](https://tex.z-dn.net/?f=3x%2B6%3D5x-4)
![3x-5x=-4-6](https://tex.z-dn.net/?f=3x-5x%3D-4-6)
![-2x=-10](https://tex.z-dn.net/?f=-2x%3D-10)
![2x=10](https://tex.z-dn.net/?f=2x%3D10)
![2x/2=10/2](https://tex.z-dn.net/?f=2x%2F2%3D10%2F2)
![x=5](https://tex.z-dn.net/?f=x%3D5)
The number is 5.
Answer:
see explanation
Step-by-step explanation:
Multiply both sides by 9 to eliminate the fraction
9K = 5(F + 459.67) ← divide both sides by 5
F + 459.67 =
K ( subtract 459.67 from both sides )
F =
K - 459.67
