The Sum Of Two Numbers Is 45 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 45 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 45
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 = 45 X - Y = 29 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 45
So ;
37 + Y = 45
Y = 45 - 37
Y = 8
Second number is 8
