Final answer:
The undoing division method involves multiplying both sides of an equation by the same number in order to preserve equality. Each term in the equation should be enclosed in small brackets, and the multiplication or division operation should be applied to each term. Multiplying both sides of the equation leads to the solution.
Step-by-step explanation:
Multiplication or division by the same number on both sides of an equation does not change equality. Remember that multiplication or division should apply to every term on either side of the equality. Enclose the side with more than one term in small brackets and then do the multiplication of division operation so that it applies to each term in the bracket. Multiplying both sides of the above equation with leads to:
