The Sum Of Two Numbers Is 83 And Their Difference Is 6
The problem given says that 2 unknown numbers are given, whose sum is equal to 83 and the difference is 6. Let's find the two numbers :When we add the two numbers :
X + Y = 83
The difference of two numbers :
X - Y = 6
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 83 X - Y = 6 2X = 89 |
Let's divide 89 to 2 for the first number "X" .
X/2 = 44.5
First number is 44.5
X + Y = 83
So ;
44.5 + Y = 83
Y = 83 - 44.5
Y = 38.5
Second number is 38.5
Question & Answer
