The Sum Of Two Numbers Is 89 And Their Difference Is 29
The problem given says that 2 unknown numbers are given, whose sum is equal to 89 and the difference is 29. Let's find the two numbers :When we add the two numbers :
X + Y = 89
The difference of two numbers :
X - Y = 29
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 89 X - Y = 29 2X = 118 |
Let's divide 118 to 2 for the first number "X" .
X/2 = 59
First number is 59
X + Y = 89
So ;
59 + Y = 89
Y = 89 - 59
Y = 30
Second number is 30
Question & Answer
