Answer: x= 2/5
Step-by-step explanation:
3(x-1) - 5 = -3(-6x+4) - 5x
Remove parenthesis
3x-3-5=18x-12-5x
Calculate and combine like terms
3x-8=13x-12
Move terms
3x-13x=-12+8
add like terms
-10x=-4
divide both sides ny -10
x=2/5

Yes, parentheses can change the order in which operations are performed in an expression.
Let us understand this with two examples.
First example.
Let us suppose we have to simplify the expression

In this expression we have evaluated subtraction first instead of multiply.
Second example.
Let us suppose we have to simplify the expression

In this expression we have evaluated multiplication first and then subtraction.
Therefore, from above two examples we can see that parentheses can change the order in which operations are performed in an expression.
C because all you need to do is compare the 2 variables and then add the variables and the multiply it and then divide it. Then your golden.
