To solve the equation 10x + 65 = 125, we need to isolate the variable x.

First, subtract 65 from both sides of the equation:

10x + 65 - 65 = 125 - 65

This simplifies to:

10x = 60

Next, divide both sides of the equation by 10 to solve for x:

10x/10 = 60/10

This simplifies to:

x = 6

Therefore, the solution to the equation 10x + 65 = 125 is x = 6.
