The Sum Of Two Numbers Is 37 And Their Difference Is 9

The problem given says that 2 unknown numbers are given, whose sum is equal to 37 and the difference is 9. Let's find the two numbers :

When we add the two numbers :
X + Y = 37

The difference of two numbers :
X - Y = 9

Solution :

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

X + Y = 37
X - Y = 9

2X = 46

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

X/2 = 23

First number is 23

X + Y = 37
So ;
23 + Y = 37
Y = 37 - 23
Y = 14

Second number is 14
