The Sum Of Two Numbers Is 75 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 75 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 75
The difference of two numbers :
X - Y = 37
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 75 X - Y = 37 2X = 112 |
Let's divide 112 to 2 for the first number "X" .
X/2 = 56
First number is 56
X + Y = 75
So ;
56 + Y = 75
Y = 75 - 56
Y = 19
Second number is 19
