The Sum Of Two Numbers Is 61 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 61 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 61
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 61 X - Y = 2 2X = 63 |
Let's divide 63 to 2 for the first number "X" .
X/2 = 31.5
First number is 31.5
X + Y = 61
So ;
31.5 + Y = 61
Y = 61 - 31.5
Y = 29.5
Second number is 29.5
Question & Answer
The Sum Of Two Numbers Is 61 And Their Difference Is 2 : 31.5 And 29.5
