The Sum Of Two Numbers Is 60 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 60 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 60
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 = 60 X - Y = 26 2X = 86 |
Let's divide 86 to 2 for the first number "X" .
X/2 = 43
First number is 43
X + Y = 60
So ;
43 + Y = 60
Y = 60 - 43
Y = 17
Second number is 17
Question & Answer
