The Sum Of Two Numbers Is 53 And Their Difference Is 16

The problem given says that 2 unknown numbers are given, whose sum is equal to 53 and the difference is 16. Let's find the two numbers :

When we add the two numbers :
X + Y = 53

The difference of two numbers :
X - Y = 16

Solution :

If we add the two equations eachother , then we can find the first number.

X + Y = 53
X - Y = 16

2X = 69

Let's divide 69 to 2 for the first number "X" .

X/2 = 34.5

First number is 34.5

X + Y = 53
So ;
34.5 + Y = 53
Y = 53 - 34.5
Y = 18.5

Second number is 18.5

Question & Answer
The Sum Of Two Numbers Is 53 And Their Difference Is 16 : 34.5 And 18.5
