The Sum Of Two Numbers Is 61 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 61 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 61
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 = 61 X - Y = 8 2X = 69 |
Let's divide 69 to 2 for the first number "X" .
X/2 = 34.5
First number is 34.5
X + Y = 61
So ;
34.5 + Y = 61
Y = 61 - 34.5
Y = 26.5
Second number is 26.5
Question & Answer
The Sum Of Two Numbers Is 61 And Their Difference Is 8 : 34.5 And 26.5
