The Sum Of Two Numbers Is 33 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 33 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 33
The difference of two numbers :
X - Y = 9
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 33 X - Y = 9 2X = 42 |
Let's divide 42 to 2 for the first number "X" .
X/2 = 21
First number is 21
X + Y = 33
So ;
21 + Y = 33
Y = 33 - 21
Y = 12
Second number is 12
