I'll do the first two to get you started

# 1

8=8v-4%28v%2B8%29 Start with the given equation.


8=8v-4v-32 Distribute.


8=4v-32 Combine like terms on the right side.


0=4v-32-8 Subtract 8 from both sides.


-4v=-32-8 Subtract 4v from both sides.


-4v=-40 Combine like terms on the right side.


v=%28-40%29%2F%28-4%29 Divide both sides by -4 to isolate v.


v=10 Reduce.


----------------------------------------------------------------------

Answer:

So the solution is v=10

=======================================================
# 2

10%281%2B3b%29=-20 Start with the given equation.


10%2B30b=-20 Distribute.


30b=-20-10 Subtract 10 from both sides.


30b=-30 Combine like terms on the right side.


b=%28-30%29%2F%2830%29 Divide both sides by 30 to isolate b.


b=-1 Reduce.


----------------------------------------------------------------------

Answer:

So the solution is b=-1
