The Sum Of Two Numbers Is 26 And Their Difference Is 19
The problem given says that 2 unknown numbers are given, whose sum is equal to 26 and the difference is 19. Let's find the two numbers :When we add the two numbers :
X + Y = 26
The difference of two numbers :
X - Y = 19
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 26 X - Y = 19 2X = 45 |
Let's divide 45 to 2 for the first number "X" .
X/2 = 22.5
First number is 22.5
X + Y = 26
So ;
22.5 + Y = 26
Y = 26 - 22.5
Y = 3.5
Second number is 3.5
Question & Answer
The Sum Of Two Numbers Is 26 And Their Difference Is 19 : 22.5 And 3.5
