I'll do the first one to get you started.

# 1
-2%282t%2B8%29%2B5=5 Start with the given equation.


-4t-16%2B5=5 Distribute.


-11-4t=5 Combine like terms on the left side.


-4t=5%2B11 Add 11 to both sides.


-4t=16 Combine like terms on the right side.


t=%2816%29%2F%28-4%29 Divide both sides by -4 to isolate t.


t=-4 Reduce.

Answer:

So the solution is t=-4
