SAT math divisibility

Given two integers a (dividend) and b (divisor), we can divide one by the other with a remainder: a=qb+r
the quotient, q indicates how many times b fits in a and the remainder r is what's left after that and hence

Therefore for your question we have

x=3*9+1=28

Hope these help!!
