Formulating systems of equations

Formular sistemas de ecuaciones

Step-by-step explanation:

Lo primero que debemos hacer es resolver una incógnita en la primera ecuación. Posteriormente, sustituimos el valor correspondiente de "x" en la segunda ecuación. Ahora, borramos el "y". Finalmente, usamos el valor de "y" para encontrar el valor de "x".

step-by-step explanation:

the inequality is:

250c+180g≥950

step-by-step explanation:

let c denotes the number of days in a week   miyoko worked as a cryptographer.

and g denotes the number of days in a week she works as a geologist.

now we are given that she earns $250 for every day she works as a cryptographer,and earns $180 for every day she works as a geologist.

now miyoko's goal is to earn more than $950 this week.

hence, the inequality could be represented as:

250c+180g≥950
