Question 835695
A more complete question is, how many night movies and how many matinee or day movies, did Antonio attend?


ASSIGN VARIABLES.
x = count of daytime movies (matinees?)
y = count of night time movies


PRICES:
Matinees are 6 dollars/movie
Night movies are 8 dollars/movie


The total of 12 means that {{{x+y=12}}}


The total spent $86 means that {{{6x+8y=86}}}


THOSE are your two simultaneous equations for the system.  Using either substitution or elimination should be a simple matter from here.  Before either method, simplify the cost equation first.  Use it as {{{3x+4y=43}}}, after both sides divided by 2.

If chose elimination, multiply the movie count equation by 3 on both sides...
