t = 131/128 = 1.023

Step-by-step explanation:

Pull out like factors :

  -768t + 786  =   -6 • (128t - 131)

Solve :    -6   =  0

Solve  :    128t-131 = 0

Add  131  to both sides of the equation :

                     128t = 131

Divide both sides of the equation by 128:

   Final

 t = 131/128 = 1.023

Have a beautiful day!
