The Sum Of Two Numbers Is 56 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 56
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 56 X - Y = 10 2X = 66 |
Let's divide 66 to 2 for the first number "X" .
X/2 = 33
First number is 33
X + Y = 56
So ;
33 + Y = 56
Y = 56 - 33
Y = 23
Second number is 23
Question & Answer
