<span>' B ' says that he starts with $50,000
and then loses $100 for each computer he sells.
If he sold 500

The only way he could earn
$75,000 from that equation would be to sell
(negative 250) computers.
That would be quite a trick, so it's most likely not 'B'.</span>
-8-5y= 12-9y
⇒ 9y -5y= 12+8
⇒ 4y= 20
⇒ y= 20/4
⇒ y= 5
Final answer: y=5~
Answer:
{y = 15/8 - (9 x)/8, y = -(7 x)/8 - 2}
{9 x + 8 y = 15, 7 x + 8 (y + 2) = 0}
Step-by-step explanation:
