Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x
Step-by-step explanation:
We have to simplify each expression for comparison
Expression 1:
[tex]6x+18-3x-9\\= 3x+9[/tex]
Expression 2:
[tex]6x-3(3x-3)\\= 6x-9x+9\\= -3x+9[/tex]
Expression 3:
[tex]-3(x-3)\\= -3x+9[/tex]
Expression 4:
[tex]-6x+3(3+3x)-6x\\= -6x+9+9x-6x\\= -3x+9[/tex]
Hence,
Equivalent expressions are:
6x-3(3x-3)
-3(x-3)
-6x+3(3+3x)-6x
