Answer:Notebook is $4Thumb drive is $23Step-by-step explanation:Let notebooks be x and thumb drives be y6x+7y=$18514x+12y=$332These two are simultaneous equation. Multiplying the first equation by 7 and second by 3 we obtain42x+49y=$129542x+36y=$996Subtracting the third equation from the fourth996-1295=-$299(36-49)y=-23y-23y=-$299y=$299/13=$23To get the value of x, we substitute the value of y into the first equation6x+(7*23)=$1856x=$185-$1616x=$24x=$4Therefore, price of notebook is $4, price of thumb drive is $23
