    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
