The Sum Of Two Numbers Is 58 And Their Difference Is 30
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 30. Let's find the two numbers :When we add the two numbers :
X + Y = 58
The difference of two numbers :
X - Y = 30
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 58 X - Y = 30 2X = 88 |
Let's divide 88 to 2 for the first number "X" .
X/2 = 44
First number is 44
X + Y = 58
So ;
44 + Y = 58
Y = 58 - 44
Y = 14
Second number is 14
Question & Answer
