the sum of two number is 42 and it's different is a 8. find the number?​

Sagot :

Answer:  17 and 25

Step-by-step explanation:

Let X and Y be the two numbers.

---------------

X + Y = 42  [sum of two numbers is 42]

X - Y = 8  [their difference is 8]

-------------------

Rearrange the last equation to

X = 8 + Y

Now enter that into the 1st equation:

X + Y = 42

(8+Y) + Y = 42

2Y = 34

Y = 17

Since X - Y = 8,

  X = 8 + 17

  X = 25

===

X + Y = ?

17 + 25 = 42  Checks

X - Y = ?

25 - 17 = 8  Checks
