The Sum Of Two Numbers Is 83 And Their Difference Is 25
The problem given says that 2 unknown numbers are given, whose sum is equal to 83 and the difference is 25. Let's find the two numbers :When we add the two numbers :
X + Y = 83
The difference of two numbers :
X - Y = 25
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 83 X - Y = 25 2X = 108 |
Let's divide 108 to 2 for the first number "X" .
X/2 = 54
First number is 54
X + Y = 83
So ;
54 + Y = 83
Y = 83 - 54
Y = 29
Second number is 29
Question & Answer
