your age now is 25.
your father's age now is 2 * 25 = 50
you will be 50 in 50 - 25 = 25 years.
your father will be 50 + 25 = 75 in 25 years.
when you are 50, your father will be 75.

i think that, algebraically, your father's age will be 25 years more than your age.
algebraically that would be y = x + 25.
y is your father's age.
x is your age.

when x = 25, then y = 25 + 25 = 50
when x = 50, then y = 50 + 25 = 75

note that, when x = 25, y is also equal to 2 * x, but that only occurs when x = 25.

to confirm, you have two equations that need to be solved simultaneously.
they are:
y = 2x
y = x + 25
replace y with 2x in the second equation to get:
2x = x + 25
subtract x from both sides of the equation to get:
2x - x = 25
solve for x to get:
x = 25.

your solution is that the algebraic equation is y = x + 25.
y is your father's age.
x is your age.
