Answer
Fill the blanks with
... subtract b, ...
... divide with m.
Work Step by Step
We need to isolate x on one side of the equation.
On the RHS, the term "+b" is removed by subtracting b from both sides.
The resulting equation is
$y-b=mx.$
Now, m is removed from x by dividing both sides with m:
$\displaystyle \frac{y-b}{m}=x.$
Fill the blanks with
... subtract b, ...
... divide with m.
