The Sum Of Two Numbers Is 35 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 35 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 35
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 35 X - Y = 17 2X = 52 |
Let's divide 52 to 2 for the first number "X" .
X/2 = 26
First number is 26
X + Y = 35
So ;
26 + Y = 35
Y = 35 - 26
Y = 9
Second number is 9
Question & Answer
