Step-by-step explanation:
Let the two numbers be X and Y.
Note: We call X and Y as variable.
A/c to statement given,
sum of two numbers is 50
X + Y = 50
X = 50 - Y
Difference of these two numbers is
X - Y = 14
50 - Y - Y = 14
50 - 2Y = 14
-2Y = 14 - 50
-2Y = -36
2Y = 36
Y = 18
X = 50 - Y
X = 50 - 18
X = 32
Difference of their cube
X³ - Y³
32³ - 18³
32768 - 5832
26936
