The Sum Of Two Numbers Is 89 And Their Difference Is 19
The problem given says that 2 unknown numbers are given, whose sum is equal to 89 and the difference is 19. Let's find the two numbers :When we add the two numbers :
X + Y = 89
The difference of two numbers :
X - Y = 19
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 89 X - Y = 19 2X = 108 |
Let's divide 108 to 2 for the first number "X" .
X/2 = 54
First number is 54
X + Y = 89
So ;
54 + Y = 89
Y = 89 - 54
Y = 35
Second number is 35
Question & Answer
