The Sum Of Two Numbers Is 64 And Their Difference Is 6

The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 6. Let's find the two numbers :

When we add the two numbers :
X + Y = 64

The difference of two numbers :
X - Y = 6

Solution :

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

X + Y = 64
X - Y = 6

2X = 70

Let's divide 70 to 2 for the first number "X" .

X/2 = 35

First number is 35

X + Y = 64
So ;
35 + Y = 64
Y = 64 - 35
Y = 29

Second number is 29
