To solve the equation (x + 7) - 25 = 13, we can start by simplifying the left side of the equation:

(x + 7) - 25 = 13

x + 7 - 25 = 13

x - 18 = 13

Next, we can isolate the variable x by adding 18 to both sides of the equation:

x - 18 + 18 = 13 + 18

x = 31

Therefore, the solution to the equation is x = 31.
