The Sum Of Two Numbers Is 17 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 17 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 17
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 17 X - Y = 5 2X = 22 |
Let's divide 22 to 2 for the first number "X" .
X/2 = 11
First number is 11
X + Y = 17
So ;
11 + Y = 17
Y = 17 - 11
Y = 6
Second number is 6
