The Sum Of Two Numbers Is 88 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 29
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 88 X - Y = 29 2X = 117 |
Let's divide 117 to 2 for the first number "X" .
X/2 = 58.5
First number is 58.5
X + Y = 88
So ;
58.5 + Y = 88
Y = 88 - 58.5
Y = 29.5
Second number is 29.5
Question & Answer
