A) \[6a9=21\]
B) a + 12 =17
C) 5a = 35
D) \[2a-(-3)=13\]
Correct Answer: C
Solution :
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.You need to login to perform this action.
