# 1



3n-5=-8%286%2B5n%29 Start with the given equation.


3n-5=-48-40n Distribute.


3n=-48-40n%2B5 Add 5 to both sides.


3n%2B40n=-48%2B5 Add 40n to both sides.


43n=-48%2B5 Combine like terms on the left side.


43n=-43 Combine like terms on the right side.


n=%28-43%29%2F%2843%29 Divide both sides by 43 to isolate n.


n=-1 Reduce.


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

Answer:

So the answer is n=-1

# 2



-%281%2B7x%29-6%28-7-x%29=36 Start with the given equation.


-1-7x%2B42%2B6x=36 Distribute.


-x%2B41=36 Combine like terms on the left side.


-x=36-41 Subtract 41 from both sides.


-x=-5 Combine like terms on the right side.


x=%28-5%29%2F%28-1%29 Divide both sides by -1 to isolate x.


x=5 Reduce.


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

Answer:

So the answer is x=5


==============================================================

# 3



-5%281-5x%29%2B5%28-8-2%29=-4x-8x Start with the given equation.


-5%2B25x-40-10=-4x-8x Distribute.


25x-55=-4x-8x Combine like terms on the left side.


25x-55=-12x Combine like terms on the right side.


25x=-12x%2B55 Add 55 to both sides.


25x%2B12x=55 Add 12x to both sides.


37x=55 Combine like terms on the left side.


x=%2855%29%2F%2837%29 Divide both sides by 37 to isolate x.


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

Answer:

So the answer is x=55%2F37 which approximates to x=1.486.
