Az-qb=yz solve for z and justify each step

Step 1:

We assume that A, q, and, b, are real numbers (where y could be a variable).

Step 2:

Terms with z to the left of the equation. Independent terms of z to the right of the equation.

Az - yz = qb

Step 3:

Common factor z.

z (A - y) = qb

Step 4:

Clear z.

z = qb / (A - y)

Answer:

z = qb / (A - y)
