The Sum Of Two Numbers Is 63 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 63 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 63
The difference of two numbers :
X - Y = 11
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 63 X - Y = 11 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 63
So ;
37 + Y = 63
Y = 63 - 37
Y = 26
Second number is 26
Question & Answer
