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
