Answer:
-4
Step-by-step explanation:
3.4+2(9.7-4.8x)=61.2
2(9.7-4.8x)=61.2-3.4
2(9.7-4.8x)=57.8
9.7-4.8x=57.8/2
9.7-4.8x=28.9
4.8x=9.7-28.9
4.8x=-19.2
x=-19.2/4.8
x=-4
Answer:
30 inkjet printers
30 laser printers
Step-by-step explanation:
Let x be inkjet printer
Let y be the laser printer
Total printer produced per day = 60
This implies that x+y = 60
The company has 120 labor hours per day. If it has 1 labor hour to make a inkjet printer and 3 labor hours to make a laser printer, we will have
x + 3y = 120
So we have
x + y = 60 ........(1)
x + 3y = 120 ........(2)
Subtract equation 1 from 2
We have
2y = 60
y = 60/2
y = 30
Put y= 30 into equation 1
x + y = 60
x + 30 = 60
x = 60 -30
x = 30
Therefore we have 30 inkjet printers and 30 laser printer.
