Answer:
The correct option is (c).
Step-by-step explanation:
The equation to be solved is:
[tex]-3(x+1)+3x=-3(x-1)+3[/tex]
The expression consist of only one variable, i.e. x.
So, to compute the value of this variable the equation has to be reduced to the form:
x = a
Thus, the correct option is (c).
Solve the equation as follows:
[tex]-3(x+1)+3x=-3(x-1)+3[/tex]
[tex]-3x-3+3x=-3x+3+3\\-3=-3x+6\\3x=6+3\\3x=9\\x=3[/tex]
