Which ordered pair is a solution to the system of linear equations? 2x + 3y= 6 –3x + 5y = 10
n200080 [17]

Answer:

(0,2)

Step-by-step explanation:

solve by addition/elimination

2x + 3y= 6

–3x + 5y = 10  

multiply first equation by 3  and second one by 2 to eliminate x)

6x+9y=18

-6x+10y=20 (add the two equations)

6x+9y-6x+10y=38

19y=38

y=38/19=2

2x+3y=6

2x=6-6

x=0

Reporting Stockholders' Equity
DaniilM [7]

The total stockholders equity based on the information given will be $8285000.

<h3>How to compute the equity?</h3>

The stockholders equity will be calculated thus:

Common stock $4480000

Excess over par = $1152000

Paid in capital = $5632000

Sale of treasury = $224,000

Total paid in capital = $5856000

Retained earnings = $2,554,000

Total = $8,410,000

Less treasury stock = 125,000

Total stockholders equity = $8,410,000 - $125000

= $8285000

Therefore, the total stockholders equity based on the information given will be $8285000.
