Beta-blockers, alpha2-adrenergic agonists, and thiazide diuretics are associated with libido changes. Testosterone is the main hormonal mediator of a manâs libido. As testosterone levels decline, sexual desire decreases; therefore medications that affect testosterone can alter the libido. Finasteride and dutasteride, 5-alpha reductase inhibitors for the treatment of benign prostate hyperplasia (BPH), decrease dihydrotestosterone levels, the active metabolite of testosterone.
Solving an equation symbolically means that expressions that may contain known variables or possibly also variables not in the original equation are admitted as solutions. For example, the equation x + y = 2x â 1 is solved for the unknown x by the solution x = y + 1, because substituting y + 1 for x in the equation results in (y + 1) + y = 2(y + 1) â 1, a true statement.
Like a Puzzle. In fact, solving an equation is just like solving a puzzle. And like puzzles, there are things we can (and cannot) do. Here are some things we can do: 1  Clear out any fractions by Multiplying every term by the bottom parts. 2  Add or Subtract the same value from both sides. 3  Divide every term by the same nonzero value. 4  Combine Like Terms. 5  Factoring. 6  Expanding (the opposite of factoring) may also help.
