The Sum Of Two Numbers Is 55 And Their Difference Is 27
The problem given says that 2 unknown numbers are given, whose sum is equal to 55 and the difference is 27. Let's find the two numbers :When we add the two numbers :
X + Y = 55
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 = 55 X - Y = 27 2X = 82 |
Let's divide 82 to 2 for the first number "X" .
X/2 = 41
First number is 41
X + Y = 55
So ;
41 + Y = 55
Y = 55 - 41
Y = 14
Second number is 14
