Answer:
5/9 & -10/3
Step-by-step explanation:
Set each to 0 and solve:
9x-5 = 0
9x=5
x=5/9
6x+20=0
6x=-20
x=-20/6
x= -10/3 or -3 1/3
Answer:
The cost of each computer before finance is:

.......(equation 1)
Now the cost of laptop is D+300:
So before finance, the cost of desktop was $2900.00 and the cost of laptop was $3200.00.
P.S: You can check if your calculation is correct by plugging the values of the cost of laptop and desktop in the equation 1.
<span>M/9+2/3=7/3
</span><span>M/9 =7/3 - 2/3
M/9 = 5/3
M = 5/3 x 9
M = 15</span>
Answer:
