The Sum Of Two Numbers Is 56 And Their Difference Is 23
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 23. Let's find the two numbers :When we add the two numbers :
X + Y = 56
The difference of two numbers :
X - Y = 23
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 56 X - Y = 23 2X = 79 |
Let's divide 79 to 2 for the first number "X" .
X/2 = 39.5
First number is 39.5
X + Y = 56
So ;
39.5 + Y = 56
Y = 56 - 39.5
Y = 16.5
Second number is 16.5
Question & Answer
