Question

resolva a equaçao 5x+1/4=10x+6/9. me ajudem

Answer 1

$\frac{5x}{1} + \frac{1}{4} = \frac{10x}{1} + \frac{6}{9} \\ \frac{20x + 1}{4} = \frac{90x + 6}{9} \\ 9(20x + 1) = 4(90x + 6) \\ 180x + 9 = 360x + 24 \\ 180x - 360x = 24 - 9 \\ - 180x = 15 ( \times - 1) \\ 180x = - 15 \\ x = \frac{ - 15}{180} \\ x = \frac{ - 1}{12}$
