Answer:

z = 30/23

Step-by-step explanation:

Solve for z over the real numbers:

6/z - 3 = 8/5

Bring 6/z - 3 together using the common denominator z:

-(3 (z - 2))/z = 8/5

Cross multiply:

-15 (z - 2) = 8 z

Expand out terms of the left hand side:

30 - 15 z = 8 z

Subtract 8 z + 30 from both sides:

-23 z = -30

Divide both sides by -23:

Answer: z = 30/23
