The Sum Of Two Numbers Is 14 And Their Difference Is 6
The problem given says that 2 unknown numbers are given, whose sum is equal to 14 and the difference is 6. Let's find the two numbers :When we add the two numbers :
X + Y = 14
The difference of two numbers :
X - Y = 6
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 14 X - Y = 6 2X = 20 |
Let's divide 20 to 2 for the first number "X" .
X/2 = 10
First number is 10
X + Y = 14
So ;
10 + Y = 14
Y = 14 - 10
Y = 4
Second number is 4
