the equations y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions. option B is correct.
<h3>What is the linear system?</h3>It is a system of an equation in which the highest power of the variable is always 1. A one-dimension figure that has no width. It is a combination of infinite points side by side.
Condition for the parallel lines.
L1, ax + bx + c = 0
L2, dx + ey + f = 0
If then lines have infinitely many solutions.
y = –3x + 4 and 3y = –9x + 12
On comparing we have
a = -3 , b = 1, and c = 4
d = -9 , e = 3, and f = 12
Then their ratio will be
Hence y = –3x + 4 and 3y = –9x + 12 have infinitely many solutions.
Thus the option B is correct.

Answer: 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.
