The Sum Of Two Numbers Is 48 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 48 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 48
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 48 X - Y = 18 2X = 66 |
Let's divide 66 to 2 for the first number "X" .
X/2 = 33
First number is 33
X + Y = 48
So ;
33 + Y = 48
Y = 48 - 33
Y = 15
Second number is 15
