Linear Equation: Removing Negative Variables
In the final step the negative variable was removed. In the book, no additional steps or explanation is given. I am assuming the correct procedure when you have a negative variable is to multiply both sides of the equation by -1.
and in addition since we multiplied by a negative quantity within an inequality we flip the sign to
Is this correct?
