The Sum Of Two Numbers Is 90 And Their Difference Is 16
The problem given says that 2 unknown numbers are given, whose sum is equal to 90 and the difference is 16. Let's find the two numbers :When we add the two numbers :
X + Y = 90
The difference of two numbers :
X - Y = 16
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 90 X - Y = 16 2X = 106 |
Let's divide 106 to 2 for the first number "X" .
X/2 = 53
First number is 53
X + Y = 90
So ;
53 + Y = 90
Y = 90 - 53
Y = 37
Second number is 37
Question & Answer
The Sum Of Two Numbers Is 90 And Their Difference Is 16 : 53 And 37
