what is the value for y in the following linear system of equations?

x - 3y = 6
x = -6

a) -6
b) -4
c) infinite number if solutions
d) 0

thank you :)

Substitute -6 for x in the first equation and solve for y.

To find the value for y in the given linear system of equations, you can substitute the value of x from the second equation into the first equation.

Given:
x = -6
x - 3y = 6

Substitute -6 for x in the second equation:
-6 - 3y = 6

Now, solve for y:
-3y = 6 + 6
-3y = 12
y = 12 / -3
y = -4

Therefore, the value for y in the given linear system of equations is -4.

The correct answer is:
b) -4
