Answer:
The number is = 16
Step-by-step explanation:
Given:
Twice the sum of a number and 2 is equal to three times the difference of the number and 4.
To find the number.
Solution:
Let the number be = ![x](https://tex.z-dn.net/?f=x)
The equation can be now written as:
![2(x+2)=3(x-4)](https://tex.z-dn.net/?f=2%28x%2B2%29%3D3%28x-4%29)
Solving for ![x](https://tex.z-dn.net/?f=x)
Using distribution:
![2x+(2\times2)=3x-(3\times4)](https://tex.z-dn.net/?f=2x%2B%282%5Ctimes2%29%3D3x-%283%5Ctimes4%29)
![2x+4=3x-12](https://tex.z-dn.net/?f=2x%2B4%3D3x-12)
Adding 12 both sides.
![2x+4+12=3x-12+12](https://tex.z-dn.net/?f=2x%2B4%2B12%3D3x-12%2B12)
![2x+16=3x](https://tex.z-dn.net/?f=2x%2B16%3D3x)
subtracting
from both sides.
![2x-2x+16=3x-2x](https://tex.z-dn.net/?f=2x-2x%2B16%3D3x-2x)
![16=x](https://tex.z-dn.net/?f=16%3Dx)
∴ ![x=16](https://tex.z-dn.net/?f=x%3D16)
Thus, the number is = 16
