what is the solution set of the equation 2z+6/z+2 = 3 − 1/z ?

note: z ≠ 0, −2

{−1, 2}

{2, 1}

{2}

{−1}

Step-by-step explanation:

First we need to specify that the equation given is wrong, it's misspelled, because that equation doesn't have solutions in the Real Numbers.

So, the equation must be expressed like this:

Now, we solve for z:

Therefore, the solution set of the equation is the last one.

PD: It's very important to write properly the equations give, otherwise all procedure would be wrong.

according to the triangle sum theorem, all the angles in a triangle must add up to 180 degrees. if we know one angle is already 90, we do 180-90=90. the other 2 angles must add up to 90, exactly.
