The Sum Of Two Numbers Is 76 And Their Difference Is 35
The problem given says that 2 unknown numbers are given, whose sum is equal to 76 and the difference is 35. Let's find the two numbers :When we add the two numbers :
X + Y = 76
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 = 76 X - Y = 35 2X = 111 |
Let's divide 111 to 2 for the first number "X" .
X/2 = 55.5
First number is 55.5
X + Y = 76
So ;
55.5 + Y = 76
Y = 76 - 55.5
Y = 20.5
Second number is 20.5
Question & Answer
The Sum Of Two Numbers Is 76 And Their Difference Is 35 : 55.5 And 20.5
