The Sum Of Two Numbers Is 73 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 29
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 73 X - Y = 29 2X = 102 |
Let's divide 102 to 2 for the first number "X" .
X/2 = 51
First number is 51
X + Y = 73
So ;
51 + Y = 73
Y = 73 - 51
Y = 22
Second number is 22
Question & Answer
