Answer:

x = 12

Step-by-step explanation:

Solve for x:

360 - 30 x = 0

Subtract 360 from both sides:

(360 - 360) - 30 x = -360

360 - 360 = 0:

-30 x = -360

Divide both sides of -30 x = -360 by -30:

(-30 x)/(-30) = (-360)/(-30)

(-30)/(-30) = 1:

x = (-360)/(-30)

The gcd of 360 and -30 is 30, so (-360)/(-30) = (-(30×12))/(30 (-1)) = 30/30×(-12)/(-1) = (-12)/(-1):

x = (-12)/(-1)

(-12)/(-1) = (-1)/(-1)×12 = 12:

Answer:  x = 12
