The Sum Of Two Numbers Is 73 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 73 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 73
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 73 X - Y = 14 2X = 87 |
Let's divide 87 to 2 for the first number "X" .
X/2 = 43.5
First number is 43.5
X + Y = 73
So ;
43.5 + Y = 73
Y = 73 - 43.5
Y = 29.5
Second number is 29.5
Question & Answer
