The Sum Of Two Numbers Is 36 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 36 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 36
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 36 X - Y = 12 2X = 48 |
Let's divide 48 to 2 for the first number "X" .
X/2 = 24
First number is 24
X + Y = 36
So ;
24 + Y = 36
Y = 36 - 24
Y = 12
Second number is 12
