\sf{\bold{\green{\underline{\underline{Solution}}}}}

⠀⠀⠀⠀

W = 7a + 4b

⠀⠀⠀⠀

  • Using equations formulae

⠀⠀⠀⠀

\sf \implies W - 4b = 7a

⠀⠀⠀⠀

\sf \implies \dfrac{W - 4b}{7} =  a

⠀⠀⠀⠀

  • checking correct option

⠀⠀⠀⠀

Option 1 :

⠀⠀⠀⠀

\sf \bigg( a = \dfrac{W - 4b}{7}  \bigg) \neq \bigg( a = \dfrac{W - 7b}{4}\bigg)

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 2 :

⠀⠀⠀⠀

\sf \bigg( a = \dfrac{W - 4b}{7}  \bigg) \neq \bigg( a = \dfrac{W}{7} - 4b \bigg)

⠀⠀⠀⠀

This option is not correct

⠀⠀⠀⠀

Option 3 :

⠀⠀⠀⠀

\sf \bigg( a = \dfrac{W - 4b}{7}  \bigg) = \bigg( a = \dfrac{W - 4b}{7}\bigg)

⠀⠀⠀⠀

This option is correct

⠀⠀⠀⠀

Option 4 :

⠀⠀⠀⠀

\sf \bigg( a = \dfrac{W - 4b}{7}  \bigg) \neq \bigg( W = \dfrac{W}{7} - 28b \bigg)

⠀⠀⠀⠀

This option is not correct
