The Sum Of Two Numbers Is 25 And Their Difference Is 1
The problem given says that 2 unknown numbers are given, whose sum is equal to 25 and the difference is 1. Let's find the two numbers :When we add the two numbers :
X + Y = 25
The difference of two numbers :
X - Y = 1
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 25 X - Y = 1 2X = 26 |
Let's divide 26 to 2 for the first number "X" .
X/2 = 13
First number is 13
X + Y = 25
So ;
13 + Y = 25
Y = 25 - 13
Y = 12
Second number is 12
