So, bike=b and accessories=a.

b+a=320

Since the bike is worth 7 times more than the accessories, the b would turn into 7a (because 7 times the cost of accessories is the cost of the bike).

The equation would now turn into 7a+a=320.

Solve for a.

7a+a=320

8a=320

a=40

Now that you know the cost of the accessories, you multiply that 40

by 7 to get the cost of the bike.

40 (7)

280

The cost of the bike is $280.

The cost of the accessories are/is $40.
