The Sum Of Two Numbers Is 60 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 60 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 60
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 60 X - Y = 10 2X = 70 |
Let's divide 70 to 2 for the first number "X" .
X/2 = 35
First number is 35
X + Y = 60
So ;
35 + Y = 60
Y = 60 - 35
Y = 25
Second number is 25
Question & Answer
