solve the equations by finding the exact solution

3=x-3

add three to each side.

6 = x

I have a feeling there was a typo, and there was more to this question.

To solve the equation 3 = x - 3, you want to isolate the variable x on one side of the equation.

Step 1: Add 3 to both sides of the equation to undo the subtraction:
3 + 3 = (x - 3) + 3
6 = x - 0

Step 2: Simplify the equation to get the exact solution:
x = 6

So, the exact solution to the equation 3 = x - 3 is x = 6.
