Let the first no. Be x
Second no. Be y
X+ y = 69 ....... 1
X - y = 39 .............. 2
Equation 1 & 2
X + y = 69
X - y = 39
2 y = 108
Y = 54 ............ 3
Equation 3 & 1
X = 15
Second no. Be y
X+ y = 69 ....... 1
X - y = 39 .............. 2
Equation 1 & 2
X + y = 69
X - y = 39
2 y = 108
Y = 54 ............ 3
Equation 3 & 1
X = 15
