The Sum Of Two Numbers Is 37 And Their Difference Is 4
The problem given says that 2 unknown numbers are given, whose sum is equal to 37 and the difference is 4. Let's find the two numbers :When we add the two numbers :
X + Y = 37
The difference of two numbers :
X - Y = 4
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 37 X - Y = 4 2X = 41 |
Let's divide 41 to 2 for the first number "X" .
X/2 = 20.5
First number is 20.5
X + Y = 37
So ;
20.5 + Y = 37
Y = 37 - 20.5
Y = 16.5
Second number is 16.5
Question & Answer
The Sum Of Two Numbers Is 37 And Their Difference Is 4 : 20.5 And 16.5
