The Sum Of Two Numbers Is 64 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 64 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 64
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 64 X - Y = 12 2X = 76 |
Let's divide 76 to 2 for the first number "X" .
X/2 = 38
First number is 38
X + Y = 64
So ;
38 + Y = 64
Y = 64 - 38
Y = 26
Second number is 26
Question & Answer
The Sum Of Two Numbers Is 64 And Their Difference Is 12 : 38 And 26
