• # question_answer Which of the following equations does not have a 5 as its solution? A) $6a9=21$                    B) a + 12 =17C) 5a = 35D) $2a-(-3)=13$

6a - 9 = 21 $\Rightarrow \,\,\,\,\,\,\,\,\,\,\,a=5$      a+12 = 17 $\Rightarrow \,\,\,\,\,\,\,\,\,\,\,a=5$          5a = 35 $\Rightarrow \,\,\,\,\,\,\,\,\,\,\,a=7$ and     2a - (- 3) = 13 $\Rightarrow \,\,\,\,\,\,\,\,\,\,\,a=5$ Hence 5a = 35 does not have a = 5 as its solution.
