To solve the equation 10.5 - x = 3, first, we need to isolate the variable x on one side of the equation.
Step 1: Subtract 10.5 from both sides of the equation:
10.5 - 10.5 - x = 3 - 10.5
-x = -7.5
Step 2: Multiply both sides of the equation by -1 to eliminate the negative sign in front of x:
(-1) * (-x) = (-1) * (-7.5)
x = 7.5
Therefore, the solution to the equation 10.5 - x = 3 is x = 7.5.
