Answer: 59/42 and 31/42
Step-by-step explanation:
Let the two numbers be x and y
x + y= 15/7........eqn. 1
x - y = 2/3.........eqn. 2
By elimination method
Subtract eqn 2 from 1
(Eliminating x)
x + y =15/7
-x - y =2/3
———————
0 + 2y = 31/21
y= (31/21)/2
y= 31/42
Substitute value of y in eqn 1
x + y = 15/7
x + 31/42 = 15/7
x = 59/42
x =59/42 and y=31/42
