Question

Z - 12 + 9 m = 5 m + 2​

Answer 1

Respuesta:

$z-12+9m=5m+2\\\\\mathrm{Restar\:}z\mathrm{\:de\:ambos\:lados}\\\\z-12+9m-z=5m+2-z\\\\\mathrm{Simplificar}\\\\-12+9m=5m+2-z\\\\\mathrm{Sumar\:}12\mathrm{\:a\:ambos\:lados}\\\\-12+9m+12=5m+2-z+12\\\\\mathrm{Simplificar}\\\\9m=5m+14-z\\\\\mathrm{Restar\:}5m\mathrm{\:de\:ambos\:lados}\\\\9m-5m=5m+14-z-5m\\\\\mathrm{Simplificar}\\\\4m=14-z\\\\\mathrm{Dividir\:ambos\:lados\:entre\:}4\\\\\frac{4m}{4}=\frac{14}{4}-\frac{z}{4}\\\\\mathrm{Simplificar}\\\\m=\frac{14-z}{4}$
