I get stuck on these.

Solve the proportion-

32 - y / y = 6/10

p + 15/42 = p - 5/14

2z/z + 7 = 24/54

7/2 = b + 4.5/b - 0.5

4/c + 1.8 = 6/c + 4.3

Would you mind explaining it to me >.<
I greatly appreciate it.

I tried finding solving this matrix but was only able to come up with the zero vector, and I'm pretty sure it does have a non trivial solution

row 1: ( 0 -1 0 ) = 0 row 2: (1 1 1) =0 row 3: ( 1 10 1) =0

the matrix is arranged with the rows on top of eachother

please help

I was really good at algebra last year and I got great grades all the way through because I could understand it. This year, however, I have geometry and I just can't grasp it and it's making me so frustrated! I don't get why it's so hard for me! It's making me feel so stupid. What can I do to make it a little easier to understand? How come I understand algebra and not geometry?
