See a solution process below:

First rewrite the expression as:

#(-3/4 xx -12)(-1)(x) =>#

#(-3/4 xx (-3 xx 4))(-1)(x) =>#

#(-3/(color(red)(cancel(color(black)(4)))1) xx (-3 xx color(red)(cancel(color(black)(4)))1))(-1)(x) =>#

#(-3/1 xx (-3 xx 1))(-1)(x) =>#

#(-3 xx -3)(-1)(x) =>#

#(9)(-1)(x) =>#

#(9 xx -1)(x) =>#

#(-9)(x) =>#

#-9x#
