1. How do you do it? I can do it normally, just I cannot rearrange it with the 0.

Can someone also explain to me what the 0 does please, and if it means anything?

Thanks!
2. take -3x and -4 to the right side with the change of signs and divide all by 5.
3. 0 makes it an equation that you can solve for y etc.
4. Y = 3/5x +20

6. 5y-3x-4=0 to make y=mx+C you have to identify what mx and c is

m is -3x and c is -4

so you have to make 5y the subject

move the -3x to the right side by adding both sides by 3x

so its 5y-4=3x

then move -4 to the other side so 5y=3x+4

then divide by 5 to make 5y, y so then its y=3/5x+4/5

good try
8. 5y - 3x - 4 = 0
5y-3x = 4
5y = 3x + 4
y = 3x/5 + 4/5
ta-daa!

Thanks. SO when you initally move the -3x to the right side, the 0 then disappears from the equation?
10. Ok we can do this step by step:

5y-3x-4=0
(+4) 5y-3x=4 (+4)
(+3x) 5y=3x+4 (+3x)
(/5) y= (3/5)x + 4/5 (/5)

So:

y = (3/5)x +4/5

Ok we can do this step by step:5y-3x-4=0(+4) 5y-3x=4 (+4)(+3x) 5y=3x+4 (+3x)(/5) y= (3/5)x + 4/5 (/5)So:y = (3/5)x +4/5

5y - 3x - 4 = 05y-3x = 45y = 3x + 4y = 3x/5 + 4/5ta-daa!

Don't post full solutions. That's of no use if OP doesn't learn through their own thinking and practice.

It's not homework. I am just re-going over some old topics just to recap in my free time, and am looking for the solution so that I can see what happens to the 0.

I dropped maths at AS I don't know the ins and outs of algebra anymore bruh

Thank you. I wasn't sure what happened to the 0, but it seems that once you move the -4 to the other side and it becomes +4 to cancel it out, that then makes the 0 disappear from the equation and gets rid of it?

So basically, the 0 is gotten rid of once you move one of the subjects to the right side of the equation, and it is just a placeholder after the = sign?

Yes sir

My apologies! I guess I just thought that OP has probably spent some time working on it, and couldn't manage it alone. Sry, anyway... I'll hint, next time

this is gcse maybe even KS3

Thanks. SO when you initally move the -3x to the right side, the 0 then disappears from the equation?

yeah, 0+3x=3x

although i agree with you to an extent, but this time last year i was also going on the internet to do this and as there was no solutions i just copied the answer. but as i wrote the explanation hopefully it'll help him

Whether you agree with me or not is irrelevant. Posting full solutions on this forum is against its rules. Just hint the OP in the right direction next time.
