Hello I have a finance problem that i am trying to solve but i havent done algebra in a while and i seem to be failing pretty hard

So Heres the entire equation

0 = 19000 + 4000 - (1000x )(((2100)(37)+4000+19000)/(2100+1000x)

Simplified it to -23000 = (1000x)(200737/1000x) but i cant seem to collect my like terms. if you could simplify the right side explaining how you do it it would be greatly appreciated. Thank you
