The Sum Of Two Numbers Is 10 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 10 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 10
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 10 X - Y = 2 2X = 12 |
Let's divide 12 to 2 for the first number "X" .
X/2 = 6
First number is 6
X + Y = 10
So ;
6 + Y = 10
Y = 10 - 6
Y = 4
Second number is 4
