Frame and solve the equations for the following statements:
The sum of the two numbers is 21 and their difference is 3. Find the numbers
Let the numbers be x and y
Now, Sum is 21
⇒x+y=21......................................(1)
and assuming that x is the Larger Number
Putting x−y=3⇒x=y+3 in eq(1) we get
⇒2y+3=21→y=9
So, x+9=21→x=12
Hence, the numbers are 9 and 12.
