Resolviendo Ecuaciones de Primer Grado

Las ecuaciones de primer grado son expresiones matemáticas donde necesitas encontrar el valor de una variable (como x, m, o w). Piensa en ellas como una balanza que debe estar equilibrada en ambos lados.

El truco principal es aislar la variable. Esto significa dejar la letra sola de un lado del signo igual. Para lograrlo, haces la operación contraria a ambos lados de la ecuación.

Por ejemplo, en m + 8 = 12, necesitas quitar el 8 que está sumando. Restas 8 de ambos lados: m + 8 - 8 = 12 - 8, entonces m = 4. ¡Así de fácil!

¡Dato curioso! Siempre puedes verificar tu respuesta sustituyendo el valor que encontraste en la ecuación original. Si ambos lados son iguales, ¡lo hiciste bien!

Operaciones inversas que necesitas recordar:

Si está sumando, resta
Si está restando, suma
Si está multiplicando, divide
Si está dividiendo, multiplica

The app is very easy to use and well designed. I have found everything I was looking for so far and have been able to learn a lot from the presentations! I will definitely use the app for a class assignment! And of course it also helps a lot as an inspiration.

This app is really great. There are so many study notes and help [...]. My problem subject is French, for example, and the app has so many options for help. Thanks to this app, I have improved my French. I would recommend it to anyone.

Wow, I am really amazed. I just tried the app because I've seen it advertised many times and was absolutely stunned. This app is THE HELP you want for school and above all, it offers so many things, such as workouts and fact sheets, which have been VERY helpful to me personally.
