The sum of two numbers is 47 and the difference is 9 what are the numbers ?

28 and 19

Step-by-step explanation:

let the 2 numbers be x and y, x > y, then

x + y = 47 → (1) ← sum of numbers

x - y = 9 → (2) ← difference of numbers

Adding the 2 equations to eliminate y

2x = 56 ( divide both sides by 2 )

x = 28

substitute x = 28 into (1) and solve for y

28 + y = 47 ( subtract 28 from both sides )

y = 47 - 28 = 19

The 2 numbers are 28 and 19

v = 1/3 a^2h
