2t−5=−10 what is t
i really need

t = -2.5 or 

Here's how we find that out:

2t -5 = -10..........................We need to get the variable, t, by itself

2t = -5................................Add 5 to both sides

t = -2.5...............................Divide both sides by 2

So, your answer is  0r -2.5

I hope this helped! Have a great day! :))
