The Sum Of Two Numbers Is 84 And Their Difference Is 22
The problem given says that 2 unknown numbers are given, whose sum is equal to 84 and the difference is 22. Let's find the two numbers :When we add the two numbers :
X + Y = 84
The difference of two numbers :
X - Y = 22
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 84 X - Y = 22 2X = 106 |
Let's divide 106 to 2 for the first number "X" .
X/2 = 53
First number is 53
X + Y = 84
So ;
53 + Y = 84
Y = 84 - 53
Y = 31
Second number is 31
Question & Answer
