The Sum Of Two Numbers Is 63 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 63 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 63
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 63 X - Y = 14 2X = 77 |
Let's divide 77 to 2 for the first number "X" .
X/2 = 38.5
First number is 38.5
X + Y = 63
So ;
38.5 + Y = 63
Y = 63 - 38.5
Y = 24.5
Second number is 24.5
Question & Answer
The Sum Of Two Numbers Is 63 And Their Difference Is 14 : 38.5 And 24.5
