The Sum Of Two Numbers Is 56 And Their Difference Is 11

The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 11. Let's find the two numbers :

When we add the two numbers :
X + Y = 56

The difference of two numbers :
X - Y = 11

Solution :

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

X + Y = 56
X - Y = 11

2X = 67

Let's divide 67 to 2 for the first number "X" .

X/2 = 33.5

First number is 33.5

X + Y = 56
So ;
33.5 + Y = 56
Y = 56 - 33.5
Y = 22.5

Second number is 22.5
