Hey, I was supposed to check if two lines have a common intersection point. I had equated the two systems of equations and now wanted to calculate the two parameters t and s to check if there is an intersection point. However, this system of equations can't be solved using the addition method. So, how…

I wanted to use the addition method instead of the substitution method, but instead of getting r=1, I get r=22/21. Can anyone spot my mistake? Here is the bill with the appointment procedure
Would it simply be smarter to use the substitution method here? I wanted to ask if someone could explain or maybe even show me how to use the addition method here, because I solved the problem using the substitution method, and when I tried to get the answer using the addition method, I got stuck…
Hello, I have to write the structural formula for the addition of 2 chlorobutane. I have written 2 but I don't know if both are correct or just one of them. Can someone please tell me if both are correct or just one of them? Please also provide an explanation. Thanks.
Hey, I know there's a mistake somewhere, but I can't find it. Can someone tell me where and explain it again?
How can I improve at math? I'm having trouble with systems of equations, powers, and power functions, as well as terms and equations, substitution methods, addition methods, and equating methods. I just don't understand the calculation method. I have no idea about these topics. Could you please explain this as simply and precisely as possible?…
