The Sum Of Two Numbers Is 56 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 56
The difference of two numbers :
X - Y = 26
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 56 X - Y = 26 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 56
So ;
41 + Y = 56
Y = 56 - 41
Y = 15
Second number is 15
Question & Answer
