Question 522607
Subtract. Simplify if possible.
{{{(4-y)/(y-6)}}}-{{{(4y-9)/(6-y)}}}
:
on the 2nd denominator we can factor out -1, to make the denominators the same
{{{(4-y)/(y-6)}}}-{{{(4y-9)/-1(y-6)}}}
:
this changes the sign so we have:
{{{(4-y)/(y-6)}}}+{{{(4y-9)/(y-6)}}}
:
the denominators are the same so we can write it, then combine like terms:
{{{((4-y)+(4y-9))/(y-6)}}} = {{{(4y-y+4-9)/(y-6)}}} = {{{(3y-5)/(y-6)}}}
