x = # $10 tickets
y = # $20 tickets
z = # $30 tickets
x + y + z = 3237
y  x = 183 or x = y  183
so 2y + z = 3420 ...... add these two equations together
10*x + 20*y + 30*z = 60750 .......... the dollar amounts
==> 10(y  183) +20y + 30z = 60750
==> 30y + 30z = 60750 + 1830
==> y + z = 2025 + 61
==> y + z = 2086
==> y = 3420  2086 = 1334
hence z = 2086 1334 = 752
and x = 1334  183 = 1151
so 1151 $10 tickets
and 1334 $20 tickets
and 752 $30 tickets
total 3237 tickets.... (check)

From KaleyK: $10 x 1,151 = $11,510
$20 x 1,334 = $26,680

$10 x 1,151 = $11,510
$20 x 1,334 = $26,680
$30 x 752 = $22,560
1,151 + 1,334 + 752 = 3,237 tickets sold
$11,510 + $26,680 +$22,560 = $60,750

From Lujk: 10x+20y+30z = 60750
x+y+z = 3237
y = x + 183
