The Sum Of Two Numbers Is 56 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 56
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 = 56 X - Y = 37 2X = 93 |
Let's divide 93 to 2 for the first number "X" .
X/2 = 46.5
First number is 46.5
X + Y = 56
So ;
46.5 + Y = 56
Y = 56 - 46.5
Y = 9.5
Second number is 9.5
Question & Answer
The Sum Of Two Numbers Is 56 And Their Difference Is 37 : 46.5 And 9.5
