I'll do the first two to get you started

# 1



51-a=1 Start with the given equation.


-a=1-51 Subtract 51 from both sides.


-a=-50 Combine like terms on the right side.


a=%28-50%29%2F%28-1%29 Divide both sides by -1 to isolate a.


a=50 Reduce.


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

Answer:

So the answer is a=50




# 2


39=u-8 Start with the given equation.


39%2B8=u Add 8 to both sides.


47=u Combine like terms on the left side.


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

Answer:

So the answer is u=47
