Answer:

We conclude that:

$b=a-cd;\quad \:c\\e \:0$

Hence, option A is true.

Explanation:

Given the expression

(a-b)/(c)=d

Solving for b

(a-b)/(c)=d

Multiply both sides by c

$(\left(a-b\right)c)/(c)=dc;\quad \:c\\e \:0$

simplify

$a-b=dc;\quad \:c\\e \:0$

Subtract a from both sides

$a-b-a=dc-a;\quad \:c\\e \:0$

Simplify

$-b=dc-a;\quad \:c\\e \:0$

Divide both sides by -1; c≠0

$(-b)/(-1)=(dc)/(-1)-(a)/(-1);\quad \:c\\e \:0$

simplify

$b=a-cd;\quad \:c\\e \:0$

Therefore, we conclude that:

$b=a-cd;\quad \:c\\e \:0$

Hence, option A is true.
