1. The 1st equation is incomplete.

2. I assume that you want to solve

Determine the domain of the equation.

Multiply through by (x - 3). You'll get:

Expand the brackets, collect like terms at LHS of the equation. You should come out with:

Apply the quadratic formula. You'll get 2 solutions. Check your solutions against the domain. The finmal result should be x = -5.
