Hey there! :)

-2t = 56

We need to isolate t. The way to do this is to divide the variable to isolation! 

Our first step is to divide both sides by -2.

-2t ÷ -2 = 56 ÷ -2

Simplify!

y = -28

So, y = -28!

We can check our work by plugging -28 as y into our given equation.

-2t = 56

-2(-28) = 58

Simplify.

58 = 58

Therefore, y = -28.

~Hope I helped!~
