how do I do this problem
3x-3=x-4
you want to get x all by its self.
subtract the x from both sides to give
2x-3=-4
add 3 to both sides
2x=-1
divide by 2 to isolate the x
x = -1/2
I still don't understand how you got the 2x?
As he said, he subtracted x from both sides of the equation.
3x - x = 2x
To solve the equation 3x - 3 = x - 4, you will need to simplify and isolate the variable x. Here's a step-by-step explanation of how to solve this problem:
Step 1: Combine like terms
To start, distribute the 3 to both terms inside the parentheses:
3x - 3 = x - 4
3x - 3x - 3 = x - 3x - 4
Simplifying this equation will yield:
-3 = -3 - x
Step 2: Simplify further
Rearrange the terms to isolate x on one side of the equation:
-3 + 3 = -x
0 = -x
Step 3: Solve for x
To find the value of x, divide both sides of the equation by -1, which will result in a reversal of the inequality sign:
0 / -1 = -x / -1
0 = x
Therefore, the solution to the equation 3x - 3 = x - 4 is x = 0.
