Answer:
![x=7](https://tex.z-dn.net/?f=x%3D7)
Step-by-step explanation:
![-3x--3+8x-24=6x+7-5x](https://tex.z-dn.net/?f=-3x--3%2B8x-24%3D6x%2B7-5x)
Two negative signs equate to a positive sign, so we can write
as just
:
![-3x+3+8x-24=6x+7-5x](https://tex.z-dn.net/?f=-3x%2B3%2B8x-24%3D6x%2B7-5x)
Add up similar terms:
![5x-21=x+7](https://tex.z-dn.net/?f=5x-21%3Dx%2B7)
Add 21 to both sides:
![5x-21+21=x+7+21](https://tex.z-dn.net/?f=5x-21%2B21%3Dx%2B7%2B21)
![5x=x+28](https://tex.z-dn.net/?f=5x%3Dx%2B28)
Subtract x from both sides:
![5x-x=x+28-x](https://tex.z-dn.net/?f=5x-x%3Dx%2B28-x)
![4x=28](https://tex.z-dn.net/?f=4x%3D28)
Divide both sides by 4:
![\frac{4x}{x} =\frac{28}{4}](https://tex.z-dn.net/?f=%5Cfrac%7B4x%7D%7Bx%7D%20%3D%5Cfrac%7B28%7D%7B4%7D)
![x=7](https://tex.z-dn.net/?f=x%3D7)
Step-by-step explanation:
There is infinitely many ratios which are equivalent to 5:9. As we know always we can write divide as fraction, so . We can multiply nominator and denominator by the any number (but the same) and get another numbers but ratio will be the same, so equivalent.
For example
10:18,
15:27
