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!~
