Hello can someone help me I’m a little confused

Answer:
18 - 2x
Step-by-step explanation:
All you need to do is distribute the first expression, and then see which option matches the original expression
3( x + 6 ) - 5x
Distributive property
3x + 18 - 5x
Combine like terms
-2x + 18
The one similar to this one is the last one
18 - 2x
Hope this helped!
