Final answer:
To solve the equation x - 125 = 600, add 125 to both sides of the equation to isolate the variable x. The solution is x = 725.
Step-by-step explanation:
To solve the equation x - 125 = 600, we need to isolate the variable x. This can be done by performing the same operation to both sides of the equation. In this case, we need to add 125 to both sides to eliminate the -125 on the left side.
x - 125 + 125 = 600 + 125
Thus, the simplified equation is x = 725.
