The Sum Of Two Numbers Is 28 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 28 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 28
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 = 28 X - Y = 2 2X = 30 |
Let's divide 30 to 2 for the first number "X" .
X/2 = 15
First number is 15
X + Y = 28
So ;
15 + Y = 28
Y = 28 - 15
Y = 13
Second number is 13
Question & Answer
