To solve for x in terms of b, simply treat b as a number, and solve for x as usual: first of all, we expand the left hand side:

Subtract 10 from both sides:

Divide both sides by -2b:

This means that in particular, if we set
, we have

Answer: n = 63

Do the opposite to find n!
3 × 21 = 63
So, to check our answer
63 ÷ 21 = 3
n = 3
