The Sum Of Two Numbers Is 51 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 51 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 51
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 51 X - Y = 17 2X = 68 |
Let's divide 68 to 2 for the first number "X" .
X/2 = 34
First number is 34
X + Y = 51
So ;
34 + Y = 51
Y = 51 - 34
Y = 17
Second number is 17
