Answer:
Let the numbers be X and Y
3X+Y =25 (Equation 1)
If instead of adding,the number is subtracted we get
3X - Y = 17 (Equation 2)
Now add equation 1 and 2 we get
(3X+Y)+(3X-Y) = 25+17
6X = 42 Thus X = 7
Now putting the value of X in Equation 1 we get
3X+Y = 25, 3*7 +Y = 25
Y = 25-21 = 4 Thus Y = 4
Thus our required numbers are X = 7 and Y = 4
