Answer:

See below

Explanation:

To solve for "a", you would first isolate ab on the right-hand side by adding "c" on both sides:

$ab-c=d\\ab-c+c=d+c\\ab=d+c$

Next, you would divide both sides by "b" to isolate "a":

$ab=d+c\\ab/ b=(d+c)/ b\\a = (d+c)/(b)$

The solution is:

Work/explanation:

To solve the given expression for a, we should isolate it by using basic algebraic operations.

The first step is to add c to each side:

$\sf{ab-c=d}$

$\sf{ab=d+c}$

Now, divide each side by b:

$\sf{a=(d+c)/(b)}$

I have solved the equation for a.
