The Sum Of Two Numbers Is 23 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 23 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 23
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 23 X - Y = 12 2X = 35 |
Let's divide 35 to 2 for the first number "X" .
X/2 = 17.5
First number is 17.5
X + Y = 23
So ;
17.5 + Y = 23
Y = 23 - 17.5
Y = 5.5
Second number is 5.5
Question & Answer
The Sum Of Two Numbers Is 23 And Their Difference Is 12 : 17.5 And 5.5
