Let's solve your equation step-by-step.

13 (7x-30) = -1209

Step 1: Simplify both sides of the equation.

13 (7x-30) = -1209

(13) (7x) + (13) (-30) = -1209 (Distribute)

91x+-390=-1209

91x-390=-1209

Step 2: Add 390 to both sides.

91x-390+390=-1209+390

91x=-819

Step 3: Divide both sides by 91.

91x91=-81991

Answer: x=-9
