The Sum Of Two Numbers Is 84 And Their Difference Is 33
The problem given says that 2 unknown numbers are given, whose sum is equal to 84 and the difference is 33. Let's find the two numbers :When we add the two numbers :
X + Y = 84
The difference of two numbers :
X - Y = 33
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 84 X - Y = 33 2X = 117 |
Let's divide 117 to 2 for the first number "X" .
X/2 = 58.5
First number is 58.5
X + Y = 84
So ;
58.5 + Y = 84
Y = 84 - 58.5
Y = 25.5
Second number is 25.5
Question & Answer
