Decision science assume more restrictions. the books pass through two departments: graphics and printing, 1. before they can be sold, x requires 3 hours in graphics and 2 hours in printing. y requires 1 hour in graphics and 1 hour in printing. there are 21 hours available in graphics and 19 hours in printing respectively. solve for x and y.

The value of x and y are 2 and 15 respectively.

Step-by-step explanation:

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.

the answer is 99.

the answer is 8/21

hope this
