Solve for n by simplifying both sides of the equation, then isolating the variable
n=9
If you divide a fraction by another fraction, this is equivalent to mupltiplying by its inverse:
so

divided by

is equivalent to

multiplied by by
which is

so the answer is

which is also 0.5
Answer:
4th one is correct for x/y
Your two equations for this question would be:
n + d = 234
5n +10d = 16.10
So with that you must take your two equations and make them equal to eachother.
Hope this helped :)
