Since we have given that
Number of hours available in graphics = 21 hours
Number of hours in printing = 19 hours
Number of hours required by x in graphics = 3
Number of hours required by x in printing = 2
Number of hours required by y in graphics = 1
Number of hours required by y in printing = 1
According to question, we get that
Using the graphing method, we get that
x = 2 and y = 15
Hence, the value of x and y are 2 and 15 respectively.
