The Sum Of Two Numbers Is 22 And Their Difference Is 4
The problem given says that 2 unknown numbers are given, whose sum is equal to 22 and the difference is 4. Let's find the two numbers :When we add the two numbers :
X + Y = 22
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 = 22 X - Y = 4 2X = 26 |
Let's divide 26 to 2 for the first number "X" .
X/2 = 13
First number is 13
X + Y = 22
So ;
13 + Y = 22
Y = 22 - 13
Y = 9
Second number is 9
Question & Answer
