Please how I solve this equation giving the domain of -3 I know that i have to replace the -3 where the x is but I do not know how to solve with the fraction. Thank you.

-2x+1/3y=4

how about multiply each term by 3, and look, no more fraction:

-6x + y = 4
now replace your x with -3
-6(-3) + y = 4
18 + y = 4
y = 4 - 18 = -14

oops. Forgot to multiply the 4

Yup, my oops. Thanks
