The Sum Of Two Numbers Is 27 And Their Difference Is 5
The problem given says that 2 unknown numbers are given, whose sum is equal to 27 and the difference is 5. Let's find the two numbers :When we add the two numbers :
X + Y = 27
The difference of two numbers :
X - Y = 5
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 27 X - Y = 5 2X = 32 |
Let's divide 32 to 2 for the first number "X" .
X/2 = 16
First number is 16
X + Y = 27
So ;
16 + Y = 27
Y = 27 - 16
Y = 11
Second number is 11
