The Sum Of Two Numbers Is 71 And Their Difference Is 3
The problem given says that 2 unknown numbers are given, whose sum is equal to 71 and the difference is 3. Let's find the two numbers :When we add the two numbers :
X + Y = 71
The difference of two numbers :
X - Y = 3
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 71 X - Y = 3 2X = 74 |
Let's divide 74 to 2 for the first number "X" .
X/2 = 37
First number is 37
X + Y = 71
So ;
37 + Y = 71
Y = 71 - 37
Y = 34
Second number is 34
