The Sum Of Two Numbers Is 88 And Their Difference Is 35
The problem given says that 2 unknown numbers are given, whose sum is equal to 88 and the difference is 35. Let's find the two numbers :When we add the two numbers :
X + Y = 88
The difference of two numbers :
X - Y = 35
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 88 X - Y = 35 2X = 123 |
Let's divide 123 to 2 for the first number "X" .
X/2 = 61.5
First number is 61.5
X + Y = 88
So ;
61.5 + Y = 88
Y = 88 - 61.5
Y = 26.5
Second number is 26.5
Question & Answer
The Sum Of Two Numbers Is 88 And Their Difference Is 35 : 61.5 And 26.5
