Write a system of linear equations to represent the situation.10. Write a matrix equation that corresponds to the system of linear equations for question 9.

Respuesta :

Let

x ----> number of adults tickets

y ---> number of students tickets

we have

x+y=200 -----> equation A

6x+4y=1,064 -----> equation B

matrix equation

[tex]\begin{bmatrix}{1} & {1} \\ {6} & {4}\end{bmatrix}\begin{bmatrix}{x} & {} \\ {y} & \end{bmatrix}=\begin{bmatrix}{200} & {} \\ {1,064} & {}\end{bmatrix}[/tex]
