Answer:

{\large{\bold{\rm{\underline{Required \; Solution}}}}}

Question -

{\sf{\dfrac{(4 x \times 4) - (7 x - 8)}{4x + 5} = - \dfrac{4}{3}}}

Solution -

\; \; \; \; \; \; \; \;{\bf{\rightarrow \dfrac{(4x \times 4) - (7x -8)}{4x + 5} = \dfrac{-4}{3}}}

Let us multiply and let's use rule of linear equation in one variable.

\; \; \; \; \; \; \; \;{\bf{\rightarrow \dfrac{16x -7x + 8}{4x + 5} = \dfrac{-4}{3}}}

Now let us cross multiply the digits.

\; \; \; \; \; \; \; \;{\bf{\rightarrow (9x+8)(3) = (-4)(4x+5)}}

Now let's multiply.

➝ 9x × 3

➝ 8 × 3

➝ -4 × 4

➝ -4 × 5

\; \; \; \; \; \; \; \;{\bf{\rightarrow 27x + 24 = -16x -20}}

Now let's combine like terms or again let's use rule of linear equation in one variable.

\; \; \; \; \; \; \; \;{\bf{\rightarrow 27x + 16x = -20 - 20}}

Now let's add or subtract

\; \; \; \; \; \; \; \;{\bf{\rightarrow 43x = -44}}

Again let's use rule of linear equation in one variable.

\; \; \; \; \; \; \; \;{\bf{\rightarrow x = \dfrac{-44}{43}}}

{\Large{\bf{\boxed{\dfrac{-44}{43}}}}}

hope it's helpful
