The Sum Of Two Numbers Is 22 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 22 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 22
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
|
X + Y = 22 X - Y = 8 2X = 30 |
Let's divide 30 to 2 for the first number "X" .
X/2 = 15
First number is 15
X + Y = 22
So ;
15 + Y = 22
Y = 22 - 15
Y = 7
Second number is 7
