The Arkham Company has a ratio of long-term debt to long-term debt plus equityof .34 and a current ratio of 1.6. Current liabilities are $900, sales are $6,320, profit margin is 9.1 percent, and ROE is 19.5 percent. What is the amount of the firm's net fixed assets?

I get to the long term debt part then cant figure out the equations.

current assets= current ratio x curr. liab

1.6x 900= 1,440.00

ni= pm x sales

.091 x 6320= 575.12

equity= ni/roe

575.12/.195= 2949.33

long term debt

.34 = ltd/(ltd+ equity)

.34= ltd/(ltd+ 2949.33)

.34(ltd+ 2949.33)= ltd

This is where I am stuck on how to proceed.
