Question 610677
I'll do the first one to get you started.


# 1

{{{-2(2t+8)+5=5}}} Start with the given equation.



{{{-4t-16+5=5}}} Distribute.



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



{{{-4t=5+11}}} Add {{{11}}} to both sides.



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



{{{t=(16)/(-4)}}} Divide both sides by {{{-4}}} to isolate {{{t}}}.



{{{t=-4}}} Reduce.

Answer:


So the solution is {{{t=-4}}}
