The Sum Of Two Numbers Is 45 And Their Difference Is 24
The problem given says that 2 unknown numbers are given, whose sum is equal to 45 and the difference is 24. Let's find the two numbers :When we add the two numbers :
X + Y = 45
The difference of two numbers :
X - Y = 24
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 45 X - Y = 24 2X = 69 |
Let's divide 69 to 2 for the first number "X" .
X/2 = 34.5
First number is 34.5
X + Y = 45
So ;
34.5 + Y = 45
Y = 45 - 34.5
Y = 10.5
Second number is 10.5
Question & Answer
