Step-by-Step Solution

To solve the equation 3−x=13 - x = 1, we will isolate the variable xx.

  • Step 1: Subtract 3 from both sides of the equation.
    3−x−3=1−3 3 - x - 3 = 1 - 3

  • Step 2: Simplify the expression.
    −x=−2 -x = -2

  • Step 3: Multiply both sides by −1-1 to solve for xx.
    x=2 x = 2

Thus, the solution to the equation is x=2 x = 2.
