The Sum Of Two Numbers Is 49 And Their Difference Is 15
The problem given says that 2 unknown numbers are given, whose sum is equal to 49 and the difference is 15. Let's find the two numbers :When we add the two numbers :
X + Y = 49
The difference of two numbers :
X - Y = 15
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 49 X - Y = 15 2X = 64 |
Let's divide 64 to 2 for the first number "X" .
X/2 = 32
First number is 32
X + Y = 49
So ;
32 + Y = 49
Y = 49 - 32
Y = 17
Second number is 17
