The Sum Of Two Numbers Is 26 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 26 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 26
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 = 26 X - Y = 5 2X = 31 |
Let's divide 31 to 2 for the first number "X" .
X/2 = 15.5
First number is 15.5
X + Y = 26
So ;
15.5 + Y = 26
Y = 26 - 15.5
Y = 10.5
Second number is 10.5
Question & Answer
