The Sum Of Two Numbers Is 64 And Their Difference Is 34
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 34. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 34
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 64 X - Y = 34 2X = 98 |
Let's divide 98 to 2 for the first number "X" .
X/2 = 49
First number is 49
X + Y = 64
So ;
49 + Y = 64
Y = 64 - 49
Y = 15
Second number is 15
Question & Answer
