Answer:


\boxed{ \bold{ \huge{\boxed{ \sf{x = 4}}}}}

Explanation:


\sf{ - 8 - x = x - 4x}

Collect like terms


\sf{ - 8 - x = - 3x}

Move 3x to left hand side and change it's sign

Similarly, move 8 to right hand side and change it's sign


\sf{ - x + 3x = 8}

Collect like terms


\sf{2x = 8}

Divide both sides of the equation by 2


\sf{ (2x)/(2) = (8)/(2) }

Calculate


\sf{x = 4}

Hope I helped!

Best regards!!
