The Sum Of Two Numbers Is 73 And Their Difference Is 21
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 21. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 21
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 73 X - Y = 21 2X = 94 |
Let's divide 94 to 2 for the first number "X" .
X/2 = 47
First number is 47
X + Y = 73
So ;
47 + Y = 73
Y = 73 - 47
Y = 26
Second number is 26
Question & Answer
The Sum Of Two Numbers Is 73 And Their Difference Is 21 : 47 And 26
