The Sum Of Two Numbers Is 73 And Their Difference Is 35

The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 35. Let's find the two numbers :

When we add the two numbers :
X + Y = 73

The difference of two numbers :
X - Y = 35

Solution :

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

X + Y = 73
X - Y = 35

2X = 108

Let's divide 108 to 2 for the first number "X" .

X/2 = 54

First number is 54

X + Y = 73
So ;
54 + Y = 73
Y = 73 - 54
Y = 19

Second number is 19
