The Sum Of Two Numbers Is 26 And Their Difference Is 18

The problem given says that 2 unknown numbers are given, whose sum is equal to 26 and the difference is 18. Let's find the two numbers :

When we add the two numbers :
X + Y = 26

The difference of two numbers :
X - Y = 18

Solution :

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

X + Y = 26
X - Y = 18

2X = 44

Let's divide 44 to 2 for the first number "X" .

X/2 = 22

First number is 22

X + Y = 26
So ;
22 + Y = 26
Y = 26 - 22
Y = 4

Second number is 4
