The Sum Of Two Numbers Is 58 And Their Difference Is 12
The problem given says that 2 unknown numbers are given, whose sum is equal to 58 and the difference is 12. Let's find the two numbers :When we add the two numbers :
X + Y = 58
The difference of two numbers :
X - Y = 12
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 58 X - Y = 12 2X = 70 |
Let's divide 70 to 2 for the first number "X" .
X/2 = 35
First number is 35
X + Y = 58
So ;
35 + Y = 58
Y = 58 - 35
Y = 23
Second number is 23
Question & Answer
