The Sum Of Two Numbers Is 32 And Their Difference Is 10
The problem given says that 2 unknown numbers are given, whose sum is equal to 32 and the difference is 10. Let's find the two numbers :When we add the two numbers :
X + Y = 32
The difference of two numbers :
X - Y = 10
Solution :
If we add the two equations eachother , then we can find the first number.
X + Y = 32 X - Y = 10 2X = 42 |
Let's divide 42 to 2 for the first number "X" .
X/2 = 21
First number is 21
X + Y = 32
So ;
21 + Y = 32
Y = 32 - 21
Y = 11
Second number is 11
