solve for x: 3(x-3)-3=-3

Question

I need help solving this 

Answer 1

 

 

 

First, move the constant from the left to the right:

 

3(x-3)-3= -3 becomes 3(x-3)= 0

 

Next, distribute the 3 into the parathesis:

 

3(x-3)=0 becomes 3x-9= 0

 

Move the constant over to the right so you can solve for x:

 

3x-9=0 becomes 3x=9

 

Solve for x by dividing both sides by three to get the answer:

x=3

 

The last step is to check the answer:

 

3(3-3)-3= -3 which becomes 3(0) -3= -3 and -3=-3, so our answer is correct.

 

Answer 2

Add 3 to both sides of the equation.

 

3(x - 3) = 0

 

 

Using the zero property of multiplication,

 

x = 3

Answer 3

3(x-3)-3=-3

 

3x -9 -3 =-3

 

3x -12=-3

3x =9

x=3
