The Sum Of Two Numbers Is 51 And Their Difference Is 2
The problem given says that 2 unknown numbers are given, whose sum is equal to 51 and the difference is 2. Let's find the two numbers :When we add the two numbers :
X + Y = 51
The difference of two numbers :
X - Y = 2
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 51 X - Y = 2 2X = 53 |
Let's divide 53 to 2 for the first number "X" .
X/2 = 26.5
First number is 26.5
X + Y = 51
So ;
26.5 + Y = 51
Y = 51 - 26.5
Y = 24.5
Second number is 24.5
Question & Answer
