Alguien me ayuda a desplegar -9x+3=5 por favor
Sidana [21]

Answer:

x=-\frac{2}{9}

Step-by-step explanation:

Supongo que te refieres a ''despejar'' la variable.

-9x+3=5

Primero, aisla los terminos independientes en la derecha y los que tienen variables, en la izquierda. En este caso, el 3 es independiente y no está en la derecha. Para poder moverlo, debo hacer la operación contraria. Por ejemplo, está siendo sumado, para ponerlo del otro lado, lo voy a restar.

-9x+3-3=5-3

Resuelvo;

-9x=2

Ahora, tengo un -9 multiplicándome la variable x, para poder deshacer esta multiplicación y dejar la variable sola, debo hacer la operación contraria; es decir, dividir por -9.

\frac{-9x}{-9}=\frac{2}{-9}

Resuelvo;

x=-\frac{2}{9}

Y, si ya no se puede seguir, este sería mi resultado.

Para comprobar si es correcto, reemplazo en la ecuación original por el valor que ya he encontrado y las respuestas deben ser iguales.

-9x+3=5\\-9(-\frac{2}{9})+3=5\\ 2+3=5\\5=5
