The Sum Of Two Numbers Is 64 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 64 X - Y = 18 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 64
So ;
41 + Y = 64
Y = 64 - 41
Y = 23
Second number is 23
Question & Answer
The Sum Of Two Numbers Is 64 And Their Difference Is 18 : 41 And 23
