I have the equation y = -2 tan (3x + 180) + 3

I need to find the x-intercepts. To do this, I know that I need to set y to equal 0 and then solve for x.

This is what I've done:

y = -2 tan (3x + 180) + 3

-3 = -2 tan (3x + 180)

3/2 = tan (3x + 180)

At this point I'm stuck. I don't know how to further isolate the x. Can I do this??

tan ^-1 3/2 = 3x + 180, solve for tan ^-1 3/2 and continue isolating x?

Thanks!!
