Answer:

Step-by-step explanation:

Assuming you want to find t.

-(-52-28) = (-4t) - (-40)         Subtract within the left parenthesis.

-(-86) = (-4t) - (-40)               Times the outside negative to the -86

86 = (-4t) - (-40)                    Times the outside negative to the -40

86 = (-4t) + 40                      Subtract 40 from the right and left

46 = -4t                                Divide by -4 on each side

t = -11.5
