The Sum Of Two Numbers Is 50 And Their Difference Is 8
The problem given says that 2 unknown numbers are given, whose sum is equal to 50 and the difference is 8. Let's find the two numbers :When we add the two numbers :
X + Y = 50
The difference of two numbers :
X - Y = 8
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 50 X - Y = 8 2X = 58 |
Let's divide 58 to 2 for the first number "X" .
X/2 = 29
First number is 29
X + Y = 50
So ;
29 + Y = 50
Y = 50 - 29
Y = 21
Second number is 21
