The Sum Of Two Numbers Is 86 And Their Difference Is 26
The problem given says that 2 unknown numbers are given, whose sum is equal to 86 and the difference is 26. Let's find the two numbers :When we add the two numbers :
X + Y = 86
The difference of two numbers :
X - Y = 26
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 86 X - Y = 26 2X = 112 |
Let's divide 112 to 2 for the first number "X" .
X/2 = 56
First number is 56
X + Y = 86
So ;
56 + Y = 86
Y = 86 - 56
Y = 30
Second number is 30
Question & Answer
