Answer 1

Explanation:

Given :-

\large \sf \bullet \: \dfrac{2 - 9z}{17 - 4z} = \dfrac{4}{5}∙

17−4z

2−9z

=

5

4

Solution :-

On cross multiplication

\implies⟹ \large \sf \: 4(17 - 4z) = 5(2 - 9z)4(17−4z)=5(2−9z)

\sf \implies 68 - 16z = 10 - 45z⟹68−16z=10−45z

\implies⟹ \large \sf \: 16z - ( - 45z )= 68 - 1016z−(−45z)=68−10

\implies⟹ \sf 29z = -5829z=−58

\implies⟹ \sf \implies x =\dfrac{-58}{29}⟹x=

29

−58

{ \textsf {\textbf{\pink{ \underline{z = - 2}}}}}

z = - 2
