The Sum Of Two Numbers Is 46 And Their Difference Is 20
The problem given says that 2 unknown numbers are given, whose sum is equal to 46 and the difference is 20. Let's find the two numbers :When we add the two numbers :
X + Y = 46
The difference of two numbers :
X - Y = 20
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 46 X - Y = 20 2X = 66 |
Let's divide 66 to 2 for the first number "X" .
X/2 = 33
First number is 33
X + Y = 46
So ;
33 + Y = 46
Y = 46 - 33
Y = 13
Second number is 13
Question & Answer
