Answer:


\boxed{ \bold{ \huge{\boxed{ \sf{x = 2}}}}}

Explanation:


\sf{5x - 4 = - 3x + 12}

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


\sf{5x + 3x - 4 = 12}

Move 4 to right hand side and change it's sign


\sf{5x + 3x = 12 + 4}

Collect like terms


\sf{8x = 12 + 4}

Add the numbers


\sf{8x = 16}

Divide both sides of the equation by 8


\sf{ (8x)/(8) = (16)/(8) }

Calculate


\sf{x = 2}

Hope I helped!

Best regards!!
