The Sum Of Two Numbers Is 86 And Their Difference Is 14

The problem given says that 2 unknown numbers are given, whose sum is equal to 86 and the difference is 14. Let's find the two numbers :

When we add the two numbers :
X + Y = 86

The difference of two numbers :
X - Y = 14

Solution :

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

X + Y = 86
X - Y = 14

2X = 100

Let's divide 100 to 2 for the first number "X" .

X/2 = 50

First number is 50

X + Y = 86
So ;
50 + Y = 86
Y = 86 - 50
Y = 36

Second number is 36
