I need help with this one pls!

Answer 1

Hi there!

`\large\boxed{b = (a)/(ac - 1)}`

We can begin by making each fraction have a common denominator:

If we make each have a common denominator of ab, we get:

`(b)/(ab) + (a)/(ab) = c`

Simplify:

`(a + b)/(ab) = c`

Multiply both sides by ab:

`a + b = cab`

Move b to the opposite side:

`a = cab - b`

Factor out b:

`a = b(ac - 1)`

Divide by (ac - 1):

`(a)/(ac - 1) = b`
