1st one: x, 2nd wud b : x+2
if its sum is 56
means:
x+ (x+2) = 56
2x = 56 -2
x= 54/2
x= 27
27 is the first odd number and the second is 27 + 2 i.e. 29
------------------------
sum of two numbers is 72
let smaller: x
larger: 4+x
its sum:
(4+x) + x = 72
4+2x=72
x= 68/2
x= 34
smaller is 34 and the larger is 34 + 4 = 38
