The Sum Of Two Numbers Is 19 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 19 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 19
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 19 X - Y = 2 2X = 21 |
Let's divide 21 to 2 for the first number "X" .
X/2 = 10.5
First number is 10.5
X + Y = 19
So ;
10.5 + Y = 19
Y = 19 - 10.5
Y = 8.5
Second number is 8.5
Question & Answer
The Sum Of Two Numbers Is 19 And Their Difference Is 2 : 10.5 And 8.5
