The Sum Of Two Numbers Is 11 And Their Difference Is 1
The problem given says that 2 unknown numbers are given, whose sum is equal to 11 and the difference is 1. Let's find the two numbers :When we add the two numbers :
X + Y = 11
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 = 11 X - Y = 1 2X = 12 |
Let's divide 12 to 2 for the first number "X" .
X/2 = 6
First number is 6
X + Y = 11
So ;
6 + Y = 11
Y = 11 - 6
Y = 5
Second number is 5
