5 large cars, 13 small cars

Let s = # of small cars (2 people)
Let l = # of large cars (4 people)

2s + 4l = 46
l + 8 = s

2(l + 8) + 4l = 46
2l + 16 + 4l = 46
6l = 30
l = 5

Check:
2s + 4l = 46
2(13) + 4(5) = 46
26 + 20 = 46
46 = 46
small car (x) seat 2 people
large car (y) seat 4 people
Total number of people is 46
8 more small cats than large cats(8+y=x)
2x+4y=46
x=8+y
2(8+y)+4y=46
16+2y+4y=46
6y=46-16
6y=30
y=30/6
y=5 aka 5 large cars

x=8+y
x=8+5
x=13 aka 13 small cars

2•13+4•5=26+20=46 seats for everyone

Good luck.
