The Sum Of Two Numbers Is 64 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 64 X - Y = 14 2X = 78 |
Let's divide 78 to 2 for the first number "X" .
X/2 = 39
First number is 39
X + Y = 64
So ;
39 + Y = 64
Y = 64 - 39
Y = 25
Second number is 25
Question & Answer
