The Sum Of Two Numbers Is 22 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 22 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 22
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 22 X - Y = 5 2X = 27 |
Let's divide 27 to 2 for the first number "X" .
X/2 = 13.5
First number is 13.5
X + Y = 22
So ;
13.5 + Y = 22
Y = 22 - 13.5
Y = 8.5
Second number is 8.5
Question & Answer
The Sum Of Two Numbers Is 22 And Their Difference Is 5 : 13.5 And 8.5
