The Sum Of Two Numbers Is 23 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 23 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 23
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 = 23 X - Y = 17 2X = 40 |
Let's divide 40 to 2 for the first number "X" .
X/2 = 20
First number is 20
X + Y = 23
So ;
20 + Y = 23
Y = 23 - 20
Y = 3
Second number is 3
