The Sum Of Two Numbers Is 26 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 26 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 26
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 26 X - Y = 12 2X = 38 |
Let's divide 38 to 2 for the first number "X" .
X/2 = 19
First number is 19
X + Y = 26
So ;
19 + Y = 26
Y = 26 - 19
Y = 7
Second number is 7
Question & Answer
