The Sum Of Two Numbers Is 24 And Their Difference Is 4

The problem given says that 2 unknown numbers are given, whose sum is equal to 24 and the difference is 4. Let's find the two numbers :

When we add the two numbers :
X + Y = 24

The difference of two numbers :
X - Y = 4

Solution :

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

X + Y = 24
X - Y = 4

2X = 28

Let's divide 28 to 2 for the first number "X" .

X/2 = 14

First number is 14

X + Y = 24
So ;
14 + Y = 24
Y = 24 - 14
Y = 10

Second number is 10
