The Sum Of Two Numbers Is 43 And Their Difference Is 4
The problem given says that 2 unknown numbers are given, whose sum is equal to 43 and the difference is 4. Let's find the two numbers :When we add the two numbers :
X + Y = 43
The difference of two numbers :
X - Y = 4
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 43 X - Y = 4 2X = 47 |
Let's divide 47 to 2 for the first number "X" .
X/2 = 23.5
First number is 23.5
X + Y = 43
So ;
23.5 + Y = 43
Y = 43 - 23.5
Y = 19.5
Second number is 19.5
Question & Answer
