The Sum Of Two Numbers Is 62 And Their Difference Is 25
The problem given says that 2 unknown numbers are given, whose sum is equal to 62 and the difference is 25. Let's find the two numbers :When we add the two numbers :
X + Y = 62
The difference of two numbers :
X - Y = 25
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 62 X - Y = 25 2X = 87 |
Let's divide 87 to 2 for the first number "X" .
X/2 = 43.5
First number is 43.5
X + Y = 62
So ;
43.5 + Y = 62
Y = 62 - 43.5
Y = 18.5
Second number is 18.5
Question & Answer
The Sum Of Two Numbers Is 62 And Their Difference Is 25 : 43.5 And 18.5
