Suppose you first want to eliminate the fraction in 4n=1/2 (2n-12). What would your first step be? Is - 2 still the solution when you start by eliminating the fraction first? Explain

    Step-by-step explanation:

    Recognize that the (1/2) in 4n=1/2 (2n-12) is a coefficient, the coefficient of the (2n - 12) term.

    Thus, multiply both sides of this equation 4n=1/2 (2n-12) by 2, to obtain:

    8n = 2n - 12

    Combining like terms, we get 6n = - 12, so that n = - 2.

    Multiplying both sides of the equation by a constant does not in any way affect your ability to find a solution and does not change the solution.
