You can put this solution on YOUR website!
x = your age.
y = your son's age.

x = y + 25
x + y = 57

since the value of x is equal to y + 25 from the first equation, replace x with y + 25 in the second equation to get:
y + 25 + y = 57
combine like terms to get:
2y + 25 = 57
subtract 25 from both sides to get:
2y = 57 - 25
simplify to get:
2y = 32
solve for y to get:
y = 32/2 = 16
you are 25 years older than your son, so you are 16 + 25 = 41.
41 + 16 = 57
41 - 16 = 25
your solution is that you are 41 and your son is 16.
