X = 15
Explanation:
9x = -135
Divide by 9 on both sides
X = -15
It is -15 since 135 is negative

\huge\text{Hey there!}

\huge\boxed{\mathsf{9x = -135}}

\huge\boxed{\text{DIVIDE 9 to BOTH SIDES}}

\huge\boxed{\mathsf{\dfrac{9x}{9}= \dfrac{-135}{9}}}

\huge\boxed{\mathsf{\bullet \ CANCEL: \dfrac{9}{9}\ because\ it \ gives\ you\ 1}}

\huge\boxed{\bullet\ \mathsf{KEEP: \dfrac{-135}{9}\ because\ it\ helps\ solve \ for}}\\\huge\boxed{\mathsf{the\ x-value}}

\huge\boxed{\mathsf{x = \dfrac{-135}{9}}}\\\\\huge\boxed{\mathsf{\dfrac{-135}{9}= x}}}

\huge\boxed{Simplify \ it\uparrow}

\huge\boxed{\mathsf{x = \bf -15}}

\huge\boxed{\textsf{Therefore, your answer is: Option D. -15 }}\huge\checkmark

LenaWriter [7]
 3k - (k-2) = (k-2) - (k+7) 3k = (k-2) - (k+7) + (k-2) 3k = 2(k-2) - (k+7) 3k = 2k - 4 - k - 7 3k = k - 11 2k = -11 
k = -5.5

. Con la finalidad de conservar el medio ambiente una de las docentes del 2do grado solicita
emmasim [6.3K]

Respuesta: 12 estudiantes trajeron pilas

Solución:

Numero total de estudiantes: 30

Sea:

x: numero de estudiantes que trajeron pilas

y: numero de estudiantes que no trajeron pilas

x+y=30 (1)

La razón entre los estudiantes que trajeron pilas y los que no trajeron es como 2 es a 3:

Razón: r=x/y=2/3 (2)

Cuantos estudiantes trajeron pilas?

x=?

Tenemos un sistema de 2 ecuaciones con 2 incógnitas:

(1) x+y=30

(2) x/y=2/3

Vamos a resolver para x. Multiplicando en cruz en la segunda ecuación:

(2) 3x=2y

Depejando y: Dividiendo ambos lados de la ecuación entre 2:

3x/2=2y/2

3x/2=y

y=3x/2

Sustituyendo y por 3x/2 en la primera ecuación:

(1) x+y=30

x+3x/2=30

Sumando los términos en el lado izquierdo de la ecuación:

(2x+3x)/2=30

5x/2=30

Despejando x:

x=30*2/5

x=60/5

x=12
