The Sum Of Two Numbers Is 47 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 47 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 47
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 47 X - Y = 12 2X = 59 |
Let's divide 59 to 2 for the first number "X" .
X/2 = 29.5
First number is 29.5
X + Y = 47
So ;
29.5 + Y = 47
Y = 47 - 29.5
Y = 17.5
Second number is 17.5
Question & Answer
