To solve a system of equations, there are two algebraic ways to solve them, one is by substitution, while the other is elimination.

1) 2a + 3b + 5 = 0

2) 2a + 4b + 10 = 0

-----------------------

-b -5 = 0 (subtract 2 from 1)

+b-b-5 = b

-5 = b

Substitute into 1) to solve for a.

2a + 3(-5) + 5 = 0

2a -15 + 5 = 0

2a -10 = 0

2a -10 + 10 = 10

2a = 10

---- ----

2 2

a=5

Substitute into 2) to check if we did it correctly.

2(5) + 4(-5) + 10 = 0

10 -20 + 10 = 0

0=0

Good luck.

3/a + 1/2 -> ((3*2) + (1*a)) / (a*2) -> (6 + a)/2a

so

(6 + a)/2a = 11/5a -> (6 + a)*5a/2a = 11 -> 6 + a = 11*2/5

so

a = 22/5 - 6 = 4.4 - 6 = -1.6

so

(6 + a)/2a = 11/5a -> (6 + a)*5a/2a = 11 -> 6 + a = 11*2/5

so

a = 22/5 - 6 = 4.4 - 6 = -1.6

First, try to check the release lever for the waste toner box. If this is OK you might be looking up to replacing the waste toner box cause this is the common reason for "Print Unable 2A" error

It is possible also that 2A is a fuser thermistor error usually caused by the fuser not heating properly and needing to be replaced. If the fuser is heating properly then the thermistat may be failing and need to be replaced.

I'm afraid a little help from a service technician is all you need, if you don't have experience for this kind of printer problem.

Good Luck!

a+b+c = 90

b=2a+2

c= a+ b - 2

substitute the second equation in the third:

c = a + (2a +2 ) - 2 = 3a and use this result in the first equation:

a + (2a +2) + 3a = 90

6a = 88

a = 14.666666

b= 2a + 2 = 27.333333

c = 90 - b - a = 48

now go study by yourself and be a good boy or girl

b=2a+2

c= a+ b - 2

(2a+3b)+(3a+2b)=9+16=25

5a+5b=25 so a+b=5

(3a+2b)-(2a+3b)=16-9=7

a-b=7

a+b=5 and a-b=7 so a=6 and b=-1 therefore 3a-2b=20

5a+5b=25 so a+b=5

(3a+2b)-(2a+3b)=16-9=7

a-b=7

a+b=5 and a-b=7 so a=6 and b=-1 therefore 3a-2b=20

I just bought one of these "dead" units for $15...I replaced the blown 2A 250V fuse with a new 2A fuse and it blew as soon as I plugged it in so then I took one of the 4A 250V fuses from the other side of the unit(located right behind the speaker output terminals) and it works perfectly now.

There is no difference between a 125v and 250v fuse. The most important thing is the 2Amp. This fuse is probably the line fuse and could be the only trouble and may have blow with a line surge. Make sure the 2A you use is a Fast Blow Type. If it does blow again you most likely have a internal power supply failure.
