What are simultaneous equations?
A set of simultaneous equations,also known as system of equations or an equation system , is a finite set of equations for which common solutions are sought.
Let x and y be the numbers.
Now according to the question,
Five times one number added to another number is 32,this can be written as
5x + y = 32 ...(i)
and three times the first number minus the other number is eight can be written as,
3x - y = 8 ...(ii)
adding eq(i) and (ii) we get,
8x = 40
⇒ x = 5
Put the value of x in eq(i) we get,
5*5 + y = 32
⇒ y = 32 - 25
⇒ y = 7
Hence the required numbers are 5 and 7.
