One number is 2 more than three times another number. it is also 8 less than the quadruple of the other. what are these two numbers?

Let x be one number  and  y the other  and we have this system

x = 3y + 2   (1)

x + 8  = 4y   (2)

 

Sub (1) into (2)  for  x  and we have

 

(3y + 2)  + 8  = 4y

 

3y + 10  = 4y       subtract 3y from both sides

 

10  =  y

 

And

 

x = 3(10) + 2

 

x =  32
