if he pays say "x" dollars for the computer then since the total is $600 he must pay 600  x dollars for the tv. his profit on the computer is \[.3x\] and his profit on the tv is \[.2(600x)\] and you know this totals 165 so set \[.3x+.2(600x)=165\] and solve for x

probably easiest to start with \[3x+2(600x)=1650\] so you don't have the messy demicals
