Answer:

x=6

Step-by-step explanation:

Given equation:

x-\left(2x-\dfrac{3x-4}{7}\right)=\dfrac{4x-27}{3}-3

Expand the left side:

\implies x-2x+\dfrac{3x-4}{7}=\dfrac{4x-27}{3}-3

Let all terms on the left side have the same denominator of 7:

\implies \dfrac{7x}{7}-\dfrac{14x}{7}+\dfrac{3x-4}{7}=\dfrac{4x-27}{3}-3

Join the terms on the left side:

\implies \dfrac{7x-14x+3x-4}{7}=\dfrac{4x-27}{3}-3

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27}{3}-3

Let all the terms on the right side have the same denominator of 3:

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27}{3}-\dfrac{9}{3}

Join the terms on the right side:

\implies \dfrac{-4x-4}{7}=\dfrac{4x-27-9}{3}

\implies \dfrac{-4x-4}{7}=\dfrac{4x-36}{3}

Cross multiply:

\implies 3(-4x-4)=7(4x-36)

Expand:

\implies -12x-12=28x-252

Add 12x to both sides:

\implies -12=40x-252

Add 252 to both sides:

\implies 240=40x

Divide both sides by 40:

\implies 6=x

\implies x=6
