The Sum Of Two Numbers Is 69 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 69 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 69
The difference of two numbers :
X - Y = 26
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 69 X - Y = 26 2X = 95 |
Let's divide 95 to 2 for the first number "X" .
X/2 = 47.5
First number is 47.5
X + Y = 69
So ;
47.5 + Y = 69
Y = 69 - 47.5
Y = 21.5
Second number is 21.5
Question & Answer
