The Sum Of Two Numbers Is 33 And Their Difference Is 7
The problem given says that 2 unknown numbers are given, whose sum is equal to 33 and the difference is 7. Let's find the two numbers :When we add the two numbers :
X + Y = 33
The difference of two numbers :
X - Y = 7
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 33 X - Y = 7 2X = 40 |
Let's divide 40 to 2 for the first number "X" .
X/2 = 20
First number is 20
X + Y = 33
So ;
20 + Y = 33
Y = 33 - 20
Y = 13
Second number is 13
Question & Answer
