Step-by-step explanation:
Assuming the given equation is
[tex]a(5 - r) = bz - 8[/tex]
To solve for r, we first divide both sides by a.
[tex]5 - r = \frac{ bz - 8}{a} [/tex]
We now subtract 5 from both sides:
[tex]- r = \frac{ bz - 8}{a} - 5[/tex]
We now divide through by - 1 to get:
[tex]r = 5 - \frac{ bz - 8}{a} [/tex]
Or
[tex]r = \frac{5a - bz + 8}{a} \: \: where \: a \ne0[/tex]
