3(y+4)-3=y+(y+5)
3y+9=2y+5
1y+9=5
1y=-4
y=-4

Six books cost 17.94. Just multiply the amount of 1 book to the number of books there are.
If we are supposed to give you like a life situation that matches the equation then I have one:
You have 42 watermelons and you need to divide them into equal groups. Let n equal the number of watermelons in each group. There are 6 groups in total. How many watermelons are in each group? (solve for n).
If this is not what you were looking for then my apologies.
