# The Sum Of Two Numbers Is 90 And Their Difference Is 29

The problem given says that 2 unknown numbers are given, whose sum is equal to 90 and the difference is 29. Let's find the two numbers :When we add the two numbers :

X + Y = 90

The difference of two numbers :

X - Y = 29

## Solution :

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

X + Y = 90 X - Y = 29 2X = 119 |

Let's divide 119 to 2 for the first number "X" .

X/2 = 59.5

First number is **59.5**

X + Y = 90

So ;

59.5 + Y = 90

Y = 90 - 59.5

Y = 30.5

Second number is **30.5**

**Question & Answer **The Sum Of Two Numbers Is 90 And Their Difference Is 29 : 59.5 And 30.5
