Answer:
→ [tex] \sf{a = \dfrac{ - 7}{ \: \: 2} }[/tex]
Step-by-step explanation:
Given Equation :
We have to find :
Solution :
[tex] \sf{ \longmapsto \: \: \: 2 - 4a = 16}[/tex]
Step 1 - Subtracting 2 on both sides :
[tex] \sf{ \longmapsto \: \: \: \cancel{2} - 4a - \cancel{2}= 16 - 2}[/tex]
[tex] \sf{ \longmapsto \: \: \: - 4a = 14}[/tex]
Step 2 : Dividing both sides with -4 :
[tex] \sf{ \longmapsto \: \: \: \dfrac{ \cancel{- 4a}}{ \cancel{- 4} \: \: } = \cancel{\dfrac{ \: \: \: 14}{ - 4}}}[/tex]
We get :
[tex] \sf{ \longmapsto \: \: \: \underline{\boxed{\bold{a = \dfrac{ - 7}{ \: \: \: 2} }}}} \: \: \: \bigstar[/tex]
>>> Therefore, value of a is "(-7)/2".
