The Sum Of Two Numbers Is 59 And Their Difference Is 13
The problem given says that 2 unknown numbers are given, whose sum is equal to 59 and the difference is 13. Let's find the two numbers :When we add the two numbers :
X + Y = 59
The difference of two numbers :
X - Y = 13
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 59 X - Y = 13 2X = 72 |
Let's divide 72 to 2 for the first number "X" .
X/2 = 36
First number is 36
X + Y = 59
So ;
36 + Y = 59
Y = 59 - 36
Y = 23
Second number is 23
Question & Answer
