Method of successive substitution Method of successive substitution In modular arithmetic, the method of successive substitution is a method of solving problems of simultaneous congruences by using the definition of the congruence equation. It is commonly applied in cases where the conditions of the Chinese remainder theorem are not satisfied. There is also an unrelated numerical-analysis method of successive substitution, a randomized algorithm used for root finding, an application of fixed-point iteration. The method of successive substitution is also known as back substitution. Consider the simple set of simultaneous congruences Now, for "x" ≡ 3 (mod 4) to be true, "x" = 3 +
None Is Too Many authors identify Frederick Blair, the head of immigration in William Lyon Mackenzie King's government, as a top official who opposed and limited Jewish immigration. They say that Blair's policy had the full support of Mackenzie King, who was prime minister 1935–48, Vincent Massey, the high commissioner to Britain, and both Anglophone and Francophone elites in general.

He replied ""None is too many"". The phrase has since entered common parlance
