The Sum Of Two Numbers Is 26 And Their Difference Is 18
The problem given says that 2 unknown numbers are given, whose sum is equal to 26 and the difference is 18. Let's find the two numbers :When we add the two numbers :
X + Y = 26
The difference of two numbers :
X - Y = 18
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 26 X - Y = 18 2X = 44 |
Let's divide 44 to 2 for the first number "X" .
X/2 = 22
First number is 22
X + Y = 26
So ;
22 + Y = 26
Y = 26 - 22
Y = 4
Second number is 4
