Question

me ajuda por favor a) 2/3+4/x+1=0
B) 2/x-1/x+2=0

Answer 1

$a) \\ \\ \dfrac{2}{4} + \dfrac{4}{x} + 1 = 0 \\ \\ \\ mmc ~=~ 4x \\ \\ \dfrac{2x + 16 + 4x}{4x} =0\\ \\ \\ \dfrac{6x + 16}{4x} =0 \\ \\ \\ \dfrac{3x + 8}{2x} = 0 \\ \\ 3x + 8 = 0 \\ \\3x = -8 \\ \\ =\ \textgreater \ x = -\dfrac{8}{3}$

===

$b) \\ \\ \dfrac{2}{x} - \dfrac{1}{x} + 2 = 0 \\ \\ \\ \dfrac{1}{x} + 2 = 0 \\ \\ \\ \dfrac{1 + 2x}{x} =0 \\ \\ \\ 1 + 2x = 0 \\ \\ 2x = -1 \\ \\ =\ \textgreater \ x = -\dfrac{1}{2}$
