The Sum Of Two Numbers Is 13 And Their Difference Is 1
The problem given says that 2 unknown numbers are given, whose sum is equal to 13 and the difference is 1. Let's find the two numbers :When we add the two numbers :
X + Y = 13
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 = 13 X - Y = 1 2X = 14 |
Let's divide 14 to 2 for the first number "X" .
X/2 = 7
First number is 7
X + Y = 13
So ;
7 + Y = 13
Y = 13 - 7
Y = 6
Second number is 6
Question & Answer
