To set up a wireless network for internet access at home, you must buy a network router for
$75. The fee for DSL service is $15 per month. If you have only $300 to spend on the setup
and service, for how many months can you get service? Let x represent the number of
months

y represents the total cost in the equation. The words per month tells you that is where the x will go. 75 doesn't change you have to pay it no matter what so it will not have the x with it.

y = 15x + 75

To solve, plugin 300 for y, then solve for x.

300 = 15x + 75

300 - 75 = 15x + 75 - 75

225 = 15x

225/15 = 15x/15

x = 15 months
