The Sum Of Two Numbers Is 35 And Their Difference Is 9
The problem given says that 2 unknown numbers are given, whose sum is equal to 35 and the difference is 9. Let's find the two numbers :When we add the two numbers :
X + Y = 35
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 = 35 X - Y = 9 2X = 44 |
Let's divide 44 to 2 for the first number "X" .
X/2 = 22
First number is 22
X + Y = 35
So ;
22 + Y = 35
Y = 35 - 22
Y = 13
Second number is 13
Question & Answer
