The Sum Of Two Numbers Is 29 And Their Difference Is 17
The problem given says that 2 unknown numbers are given, whose sum is equal to 29 and the difference is 17. Let's find the two numbers :When we add the two numbers :
X + Y = 29
The difference of two numbers :
X - Y = 17
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 29 X - Y = 17 2X = 46 |
Let's divide 46 to 2 for the first number "X" .
X/2 = 23
First number is 23
X + Y = 29
So ;
23 + Y = 29
Y = 29 - 23
Y = 6
Second number is 6
