The Sum Of Two Numbers Is 54 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 54 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 54
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 = 54 X - Y = 8 2X = 62 |
Let's divide 62 to 2 for the first number "X" .
X/2 = 31
First number is 31
X + Y = 54
So ;
31 + Y = 54
Y = 54 - 31
Y = 23
Second number is 23
