The Sum Of Two Numbers Is 45 And Their Difference Is 11
The problem given says that 2 unknown numbers are given, whose sum is equal to 45 and the difference is 11. Let's find the two numbers :When we add the two numbers :
X + Y = 45
The difference of two numbers :
X - Y = 11
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 45 X - Y = 11 2X = 56 |
Let's divide 56 to 2 for the first number "X" .
X/2 = 28
First number is 28
X + Y = 45
So ;
28 + Y = 45
Y = 45 - 28
Y = 17
Second number is 17
