Question

5/6m-5/12=7/8m+2/3
respuesta de esta ecuacion lineal de primer grado

Answer 1

$\frac{5m}{6} - \frac{5}{12} = \frac{7m}{8} + \frac{2}{3} \\ \\ \frac{10m-5}{12} = \frac{21m+16}{24} \\ \\ 24(10m-5) = (21m+16)12\\ \\ 240m - 120 = 252m + 192\\ \\ -192 - 120 = 252m -240m \\ \\ -312 = 12m \\ \\ m = -\frac{312}{12} = -\frac{156}{6} = -\frac{78}{3} = -26$
