The Sum Of Two Numbers Is 56 And Their Difference Is 4
The problem given says that 2 unknown numbers are given, whose sum is equal to 56 and the difference is 4. Let's find the two numbers :When we add the two numbers :
X + Y = 56
The difference of two numbers :
X - Y = 4
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 56 X - Y = 4 2X = 60 |
Let's divide 60 to 2 for the first number "X" .
X/2 = 30
First number is 30
X + Y = 56
So ;
30 + Y = 56
Y = 56 - 30
Y = 26
Second number is 26
