let S equal the cost of the skateboard.

they didn't give you this variable, so select it yourself.

you could use any variable name, but S is pretty good since it's the first letter of skateboard and it's not being used anywhere else in the equation.

you are given that H equal the cost of one helmet.

this means that the cost of two helmets is equal to 2H.

you are given that the total cost equals D.

your equation is S + 2H = D

this means thsat the cost of one skateboard and two helmets is equal to D dollars.

subtract 2H from both sides of the equation to get:

S = D - 2H

since S = cost of the skateboard, then that's your answer.

the cost of the skateboard is represented by D - 2H.
