Reserved seats for the football game cost $4.00 each and general admission tickets for $3.00 each. after the game was over, it was found that 1787 total tickets were sold and $5792 was made. find the number each sold . show your work

Equation for tickets sold:                        Equation for money made:
x+y=1787                                              4x+3y=5792
Solve for x using substitution:
x=1787-y
Plug it into the other equation to find the value of y:
4(1787-y)+3y=5792
7148-4y+3y=5792
-y=-1356
y=1356
Now plug y back into any equation:
x+1356=1787
x=431

1356 general admission tickets were sold, and 431 reserved seats were sold.
