The Sum Of Two Numbers Is 35 And Their Difference Is 22
The problem given says that 2 unknown numbers are given, whose sum is equal to 35 and the difference is 22. Let's find the two numbers :When we add the two numbers :
X + Y = 35
The difference of two numbers :
X - Y = 22
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 35 X - Y = 22 2X = 57 |
Let's divide 57 to 2 for the first number "X" .
X/2 = 28.5
First number is 28.5
X + Y = 35
So ;
28.5 + Y = 35
Y = 35 - 28.5
Y = 6.5
Second number is 6.5
Question & Answer
The Sum Of Two Numbers Is 35 And Their Difference Is 22 : 28.5 And 6.5
