Multiply each side by 1/3
Multiply each side by -9
Multiply each side by -9
Divide each side by 1/3
Divide each side by 1/3
Divide each side by 3
The first step in solving the equation 13x = -9 is to divide each side by 13. This step will allow us to isolate the variable x on one side of the equation. By dividing each side by 13, we are essentially undoing the multiplication of 13 on the left side.
So the correct first step is to select "Divide each side by 13" or "Divide each side by 3" from the given options.
