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

# 1
-8%28-x%2B2%29=32 Start with the given equation.


8x-16=32 Distribute.


8x=32%2B16 Add 16 to both sides.


8x=48 Combine like terms on the right side.


x=%2848%29%2F%288%29 Divide both sides by 8 to isolate x.


x=6 Reduce.


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

Answer:

So the solution is x=6

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

10%281-4x%29-5=85 Start with the given equation.


10-40x-5=85 Distribute.


-40x%2B5=85 Combine like terms on the left side.


-40x=85-5 Subtract 5 from both sides.


-40x=80 Combine like terms on the right side.


x=%2880%29%2F%28-40%29 Divide both sides by -40 to isolate x.


x=-2 Reduce.


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

Answer:

So the solution is x=-2
