 Words……  Symbols  When you divide each side of an equation by the same nonzero number, the two sides remain equal.  For any number a, b, c, where c 0, then a/c = b/c

 Example:  3x= -12  3 3  X= -4 Divide the left side of the equation by 3 to undo the multiplication 3 x Divide the right side, by the same (3), to balance.

 Words  Symbols  When you multiply each side of an equations by the same number, the two sides remain equal.  For any number a, b, and c, if a = b, then ac=bc.

 Example X = 7 6  X = 7  6  (X) 6= (7)6  (6)  X=42

 Solve  Y = -9  -4  Y = -9 (-4)  -4(-4)  Y= -9(-4)  Same sign=positive  Y= 36

 In ya’ll textbooks..  Page 117  We are doing #1-10 as a family ….  Page 118  #11-38  Ya’ll are on your OWN!!!! HAHAHA How cute!!
