Answer:

Step-by-step explanation:

If you let y=2x, you can plug it into the other equation.

x+2x=-9

Then solve that equation.

3x=-9

x=-3

Then use y=2x to find y.

y=2(-3)=-6

y=-6

Ulleksa [173]

Based on the net working capital and the current assets, the current ratio of the firm is 2.92

<h3>What is the firm's current ratio?</h3>

First, find the current liabilities:

= Current assets - Net working capital

= 3,500 - 2,300
