To all math pros, how do I solve this problem? Could you solve it and then take a photo of it and post it? I always get something different with the problems except for the first one which is scribbled in red. I understand that one but not the others.

Loading...Hello, it's me again, Sorry if I'm annoying you but I'm not making any progress with a math transformation problem: 1/f=1/g+1/bf=? So you have to transform it for f. But I don't know how to get rid of the fraction. It would be really nice if someone could help me, as I have a test…
Hi everyone, how can I determine if terms are equivalent? How can I simplify them? In b), the terms look more complicated…
Hey, What is the molecular and structural formula of radium? I need this for a creative class assignment but I can't find anything about it on the internet. I urgently need help 😨
Good evening, I'm in a bind. My math teacher is giving us mock exams for our oral Abitur exam. The last question is: Show that the graph of sin(x^-1) has more than two zeros in the range from 0 to 1. However, I really can't figure out how to prove it. I hope someone can…
no idea what you did in the third line
in I is that y=x+1 is ….so you can replace in II y with x+1
-2x + 3*(x+1) = 1

What are you getting out and how did you expect it?
Then you can go to troubleshooting.
I don’t think I don’t know how to calculate that I should try some methodologies who knows if they exist
So the basic principle is that you use the first equation in the second.
Example for b)
You set x+1 for y in the second equation
You will then receive -2x + 3*(x+1)=2
Now you release the clamp and reckon everything with x and everything without.
After that, you change the x on one side of the = and the rest on the other side.
If you then get x=? out, you can insert it into the first equation and get y
How to do it with c) and d) in the same principle
I’ll write it differently, maybe it’ll be more obvious:
II) -2*x + 3*y = 2
-2*x + 3* (x+1) = 2
Now the error comes in your equation, because you’ve been counting 3*1, but not 3*x.
It should mean:
-2*x + 3*x + 3*1 = 2
You can also write
-2*x + 3*x + 3*1 = 2
Now everything with x on one side and the rest on the other from = and then it should fit
you can solve the b
Where does it come from?
