Cuanto es la respuesta de -126=14k?

N76 [4]

Answer:

$\boxed{ \bold{ \huge{ \boxed{ \text{k = - 9}}}}}$

Step-by-step explanation:

$\star{ \text{ - 126 = 14k}}$

$\text{step \: 1 \: : Intercambia los lados de la ecuación}$

$\hookrightarrow{ \sf{14k = - 126}}$

$\text{step \: 2 : Divide ambos lados por 14}$

$\hookrightarrow{ \sf{ \frac{14k}{14} = \frac{ - 126}{14}}}$

$\text{step \: 3 \: : Calcular}$

$\hookrightarrow{ \sf{k = - 9}}$

$\text{el valor de k es - 9}$

------------------------------------------------------------

Translation in English:

Step 1 : Swap the sides of the equation

Step 2 : Divide both sides by 14

Step 3 : Calculate
