SOLVING STEP BY STEP:


(8)/(9)(54x-36)+2=- (3)/(4)(-40+16x)+90x\\ \\ (8*54x)/(9)- (8*36)/(9)+2= (3*40)/(4)- (3*16x)/(4)+90x\\ \\ (432x)/(9)- (288)/(9)+2= (120)/(4)- (48x)/(4)+90x\\ \\48x-32+2=30-12x+90x\\ \\48x-30=30+78x\\ \\-30-30=78x-48x\\ \\-60=30x\\ \\ (-60)/(30)=x\\ \\\boxed{ \boxed{-2}}=x\ ===>\ The\ great\ answer.


TESTING:


(8)/(9)(54(-2)-36)+2=- (3)/(4)(-40+16(-2))+90(-2)\\ \\ (8)/(9)(-108-36)+2=- (3)/(4)(-40-32)-180\\ \\ (8)/(9)(-144)+2=- (3)/(4)(-72)-180\\ \\- (8*144)/(9)+2= (3*72)/(4)-180\\ \\ -(1152)/(9)+2= (216)/(4)-180\\ \\-128+2=54-180\\ \\\boxed{-126}=\boxed{-126}\quad\checkmark\ Correct.
GOOD LUCK...!!!
