The Sum Of Two Numbers Is 83 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 83 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 83
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 83 X - Y = 3 2X = 86 |
Let's divide 86 to 2 for the first number "X" .
X/2 = 43
First number is 43
X + Y = 83
So ;
43 + Y = 83
Y = 83 - 43
Y = 40
Second number is 40
Question & Answer
