The Sum Of Two Numbers Is 90 And Their Difference Is 14
The problem given says that 2 unknown numbers are given, whose sum is equal to 90 and the difference is 14. Let's find the two numbers :When we add the two numbers :
X + Y = 90
The difference of two numbers :
X - Y = 14
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 90 X - Y = 14 2X = 104 |
Let's divide 104 to 2 for the first number "X" .
X/2 = 52
First number is 52
X + Y = 90
So ;
52 + Y = 90
Y = 90 - 52
Y = 38
Second number is 38
Question & Answer
The Sum Of Two Numbers Is 90 And Their Difference Is 14 : 52 And 38
