Solve -4(5-2n)=8(-6-5n)         Use distributive property



      -4(5) -4(-2n) = 8(-6) +8(-5n)



           -20 + 8n = -48 - 40n          Simplify.subtract 8n both sides.

                                         Add 48 both sides.

                48n = -28                Divide both sides by 48



                        28

                  n = - ___           Reduce to lowest term

                        48

 

                         7

                  n = - ____

                         12



Checking:



  -4(5-2n) = 8(-6-5n)



 -4(5-2(-7/12))=8(-6-5(-7/12))



  -4(5+7/6) = 8(-6+35/12)



  -20 + 28/6 = -48 + 70/3



   -120 - 28    -288 + 140

  ___________ = __________

       6             6



        -148        -148

       _______ = _________   ---->> true

         6           6
