hi everybody... i would like to learn how can i resolve 2 or more ecuations at the same time with the classpad
for example

a+b=1
d+b+2c=0
2c+a=0
-a+d+2b=3

that is just an example i didn`t resolve it yet... so a dont know the answer

but if yopu know how to resolve it... please let me know....

thx see you later

For linear equations you can use command from 2D keyboard. Just enter to 2D keyboard, tap double-down-arrow (to access second template page) and the first template at second row. If you have n equations you should tap (n-1)-times on this template to input n rows (e.g. 1 tap = 2 equations, 2 taps = 3 equations etc.).

You can see { and some empty fields. Click on the left side between { and |. Enter one equation per field. Tap to the right side of | and enter names of variables separated by comma (e.g. x,y,z). These variables will be solved. Press EXE' /> or tap EXE' /> on virtual keyboard.

En el teclado virtual eliges la opci?n 2D e introduces los coeficientes y los t?rminos independientes como una matriz. Almacenas la matriz en una variable a la que le das el nombre que quieras.
Luego ejecutas el comando rref(variable) y ah? tienes las soluciones. Adem?s con este sistema podr?s resolver sistemas de ecuaciones en el que el n?mero de ecuaciones no coincida con el de inc?gnitas y podr?s discutir si es posible solucionarlos en funci?n de un par?metro.

Ejemplo:

matrix ->a

rref(a)

On the virtual keyboard choose the 2D option and introduce the coefficent and the independent terms like a matrix. Store the matrix in a variable.
Then execute the rref(variable) command, and you will have the solutions.

Example:

matrix ->a

rref(a)
