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
