The Sum Of Two Numbers Is 43 And Their Difference Is 3

The problem given says that 2 unknown numbers are given, whose sum is equal to 43 and the difference is 3. Let's find the two numbers :

When we add the two numbers :
X + Y = 43

The difference of two numbers :
X - Y = 3

Solution :

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

X + Y = 43
X - Y = 3

2X = 46

Let's divide 46 to 2 for the first number "X" .

X/2 = 23

First number is 23

X + Y = 43
So ;
23 + Y = 43
Y = 43 - 23
Y = 20

Second number is 20
