The Sum Of Two Numbers Is 88 And Their Difference Is 25

The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 25. Let's find the two numbers :

When we add the two numbers :
X + Y = 88

The difference of two numbers :
X - Y = 25

Solution :

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

X + Y = 88
X - Y = 25

2X = 113

Let's divide 113 to 2 for the first number "X" .

X/2 = 56.5

First number is 56.5

X + Y = 88
So ;
56.5 + Y = 88
Y = 88 - 56.5
Y = 31.5

Second number is 31.5

Question & Answer
The Sum Of Two Numbers Is 88 And Their Difference Is 25 : 56.5 And 31.5
