Suppose the two numbers are x and y. According to the question;

x+Y=29 EQ1
x-y=17 EQ2

x=y+17 EQ3
put in the first equation
y+17+y=29
2y+17=29
2y=29-17
2y=12
y=12/2
y=6
Put the value of y in EQ3
x=y+17
x=6+17
x=23

so two numbers are 23 and 6

Let the two numbers are x and y
then, x+y=29.....(1)
x-y=17.....(2)
adding eq.(1) and eq.(2)
2x=46
x=23
putting the value of x into eq.(1)
23+y=29
y=6
