The Sum Of Two Numbers Is 35 And Their Difference Is 15
The problem given says that 2 unknown numbers are given, whose sum is equal to 35 and the difference is 15. Let's find the two numbers :When we add the two numbers :
X + Y = 35
The difference of two numbers :
X - Y = 15
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 35 X - Y = 15 2X = 50 |
Let's divide 50 to 2 for the first number "X" .
X/2 = 25
First number is 25
X + Y = 35
So ;
25 + Y = 35
Y = 35 - 25
Y = 10
Second number is 10
