The Sum Of Two Numbers Is 84 And Their Difference Is 38

The problem given says that 2 unknown numbers are given, whose sum is equal to 84 and the difference is 38. Let's find the two numbers :

When we add the two numbers :
X + Y = 84

The difference of two numbers :
X - Y = 38

Solution :

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

X + Y = 84
X - Y = 38

2X = 122

Let's divide 122 to 2 for the first number "X" .

X/2 = 61

First number is 61

X + Y = 84
So ;
61 + Y = 84
Y = 84 - 61
Y = 23

Second number is 23
