The Sum Of Two Numbers Is 35 And Their Difference Is 27
The problem given says that 2 unknown numbers are given, whose sum is equal to 35 and the difference is 27. Let's find the two numbers :When we add the two numbers :
X + Y = 35
The difference of two numbers :
X - Y = 27
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 35 X - Y = 27 2X = 62 |
Let's divide 62 to 2 for the first number "X" .
X/2 = 31
First number is 31
X + Y = 35
So ;
31 + Y = 35
Y = 35 - 31
Y = 4
Second number is 4
