The Sum Of Two Numbers Is 42 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 42 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 42
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 42 X - Y = 2 2X = 44 |
Let's divide 44 to 2 for the first number "X" .
X/2 = 22
First number is 22
X + Y = 42
So ;
22 + Y = 42
Y = 42 - 22
Y = 20
Second number is 20
