Problem

One number is eight less than five times another. If the sum of the two numbers is 28, find

the two numbers.(separate your answers using commas)

Solution

for this case we can define the following notation:

Let x and y the two numbers and we have:

x= 5y -8

and we also know that:

x+ y = 28

Replacing we got:

5y -8 +y = 28

6y = 28+8

6y= 36

And y = 6

And for x we got:

x= 5*6 -8= 30 -8 = 22
