check this please
Please check your typing, and use brackets to avoid ambiguity.
in the problem there are no brackets
x over x minus x/over x-4 equal -4 over x-4 solve each rational equation if it has no equation state so. simply with necessary
Please help me
So it is
[x/(2-x)]/(x-4) = -4/(x-4) ?
Where does the third equality come from ?
Can you see why brackets are absolutely necessary here?
ok, first multiply both sides by x-4 to get
x/(2-x) = -4
now multiply both sides by 2-x
x = -4(2-x)
x = -8 + 4x
-3x = -8
x = 8/3
Lastly, what does "...if it has no equation state so. simply with necessary " mean ?
