The Sum Of Two Numbers Is 63 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 63 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 63
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 63 X - Y = 17 2X = 80 |
Let's divide 80 to 2 for the first number "X" .
X/2 = 40
First number is 40
X + Y = 63
So ;
40 + Y = 63
Y = 63 - 40
Y = 23
Second number is 23
Question & Answer
