The Sum Of Two Numbers Is 70 And Their Difference Is 37
The problem given says that 2 unknown numbers are given, whose sum is equal to 70 and the difference is 37. Let's find the two numbers :When we add the two numbers :
X + Y = 70
The difference of two numbers :
X - Y = 37
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 70 X - Y = 37 2X = 107 |
Let's divide 107 to 2 for the first number "X" .
X/2 = 53.5
First number is 53.5
X + Y = 70
So ;
53.5 + Y = 70
Y = 70 - 53.5
Y = 16.5
Second number is 16.5
Question & Answer
The Sum Of Two Numbers Is 70 And Their Difference Is 37 : 53.5 And 16.5
