#x=2#

#15x+6x(2-3x)=9x(5-2x)-36#

Open the brackets and simplify. The product of a positive and a negative is a negative.

#15x+12x-18x²=45x-18x²-36#

#27x-18x²=45x-18x²-36#

Cancel similar terms on either side.

#27xcancel(-18x²)=45xcancel(-18x²)-36#

#27x=45x-36#

Add #36# to both sides.

#36+27x=45x#

Subtract #27x# from each side.

#36=18x#

Divide both sides by #18#.

#2=x# or #x=2#
