The Sum Of Two Numbers Is 88 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 88 X - Y = 17 2X = 105 |
Let's divide 105 to 2 for the first number "X" .
X/2 = 52.5
First number is 52.5
X + Y = 88
So ;
52.5 + Y = 88
Y = 88 - 52.5
Y = 35.5
Second number is 35.5
Question & Answer
The Sum Of Two Numbers Is 88 And Their Difference Is 17 : 52.5 And 35.5
