I'm not quite sure what I'm doing wrong, but I keep getting the answer of 50. If anyone could show me how to do this problem that would be very appreciated.

50 is correct.
If the question says is another option I think the question indicates it as wrong
\(5800 - 8x = 4200 + 24x\)
\(1600 = 32 x\)
\(x = 50\)
Hope this helps
