The Sum Of Two Numbers Is 56 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 56
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 = 56 X - Y = 9 2X = 65 |
Let's divide 65 to 2 for the first number "X" .
X/2 = 32.5
First number is 32.5
X + Y = 56
So ;
32.5 + Y = 56
Y = 56 - 32.5
Y = 23.5
Second number is 23.5
Question & Answer
