Guitar Practice You practice playing your guitar every day. You spend 15 minutes practicing chords and the rest of the time practicing a new song. So the total number of minutes y you practice for the week is given by y 5 7(15 1 x), where x is the number of minutes you spend on practicing a new song.
a. Solve the equation for x.
b. How many minutes did you spend on a new song if you practiced 210 minutes last week? 245 minutes? 315 minutes?
An equation needs an equal (=) sign. Where is yours?
