r=y(r+A)

Solution for r=y(r+A) equation:

Simplifying
r = y(r + A)

Reorder the terms:
r = y(A + r)
r = (A * y + r * y)

Reorder the terms:
r = (ry + yA)
r = (ry + yA)

Solving
r = ry + yA

Solving for variable 'r'.

Move all terms containing r to the left, all other terms to the right.

Add '-1ry' to each side of the equation.
r + -1ry = ry + -1ry + yA

Combine like terms: ry + -1ry = 0
r + -1ry = 0 + yA
r + -1ry = yA

Combine like terms: yA + -1yA = 0
r + -1ry + -1yA = 0
