Solve 10a  5b = 25 for b.
f) b = 10a + 25
g) b = 10a  25
h) b = 2a +5
i) b = 2a  5
What exactly are they asking me to do here? Can I get at least one with a step by step, then I'll do the others? And, then you can check my answers. Thanks :)

10a5b=25 solve for b.
10a25=5b
2a5=b

Bobpursley told you the answer and showed you how to solve it. What more do you want?

to solve for b, you want to get b all by itself on one side of the equation.
The trick is to add/subtract and multiply/divide, keeping in mind that what you do to one side of the equation, you must also do to the other side, so they stay equal.
So, bob's first step was to
add 5b and subtract 25 from both sides. At that point, all the b stuff was on one side of the equation.
Then he divided both sides by 5.
At that point, b was all alone.

2a 25
subtract and add so b is alone on one side, then divide by five on the whole equation to get what b is. We will survive Geometry!

i meant: 2a5
Not b=2a25!
