The Sum Of Two Numbers Is 40 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 40 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 40
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 = 40 X - Y = 14 2X = 54 |
Let's divide 54 to 2 for the first number "X" .
X/2 = 27
First number is 27
X + Y = 40
So ;
27 + Y = 40
Y = 40 - 27
Y = 13
Second number is 13
