The Sum Of Two Numbers Is 24 And Their Difference Is 16
The problem given says that 2 unknown numbers are given, whose sum is equal to 24 and the difference is 16. Let's find the two numbers :When we add the two numbers :
X + Y = 24
The difference of two numbers :
X - Y = 16
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 24 X - Y = 16 2X = 40 |
Let's divide 40 to 2 for the first number "X" .
X/2 = 20
First number is 20
X + Y = 24
So ;
20 + Y = 24
Y = 24 - 20
Y = 4
Second number is 4
