I cant seem to figure this one out. :(

Todd has 48 words to spell for a puzzle. As an incentive, his mom offers to give him 10 cents for each correct word if Todd gives her 6 cents for each incorrect word. If Todd gets $1.92, how many words did he spell correctly?
 
let x = number of correct words

then 48 - x = number of incorrect words

(.10)x - (.06)(48 - x) = 1.92

solve for x
