Answer:


  • -3\left(2x-9\right)=3\left(16-x\right)

  • -3\left(2x-9\right)

  • =-3\cdot \:2x-\left(-3\right)\cdot \:9

  • -3\cdot \:2x+3\cdot \:9

  • =-6x+3\cdot \:9

  • =-6x+27

  • 3\left(16-x\right)

  • =3\cdot \:16-3x

  • =48-3x

  • -6x+27=48-3x

  • -6x+27-27=48-3x-27

  • -6x=-3x+21

  • -6x+3x=-3x+21+3x

  • -3x=21

  • (-3x)/(-3)=(21)/(-3)

  • x=-7
