x televisions and y video recorders
The value of the stock at the beginning of the week, at $360 for each television and $270 for each video recorder, was $55,530:
The sales total for the week, consisting of 3/4 of the televisions and 1/3 of the video recorders, was $32,310:
Multiply the second equation by 3 and subtract the first equation to eliminate y and solve for x. Then use that x value in either original equation to find y.
