How to solve simultaneous congruences?
Example: Solve the simultaneous congruences x ? 6 (mod 11), x ? 13 (mod 16), x ? 9 (mod 21), x ? 19 (mod 25). Solution: Since 11, 16, 21, and 25 are pairwise relatively prime, the Chinese Remainder Theorem tells us that there is a unique solution modulo m, where m = 11 ? 16 ? 21 ? 25 = 92400. We apply the technique of the Chinese ...
Does x = 1 solve the second congruence?
Thus x = 2 ? 21 ? 1 is still a solution of x ? 2mod5 while it is also congruent to 0 modulo 3 and 7. So now we've found a solution to the second congruence which doesn't interfere with the first and last congruences. Finally, x = 1 solves the third congruence but not the first two. So you compute (5 ? 7) ? 1 = 35 ? 1 mod 3.
What is a simultaneous equation used for?
Simultaneous equations can be used to solve a wide range of problems in finance, science, engineering, and other fields. They are often used to find the values of variables that make multiple equations or expressions true at the same time. What are the methods for solving Simultaneous Equations?
How do you solve simultaneous equations with two variables?
To solve linear simultaneous equations with two variables by graphing, plot both equations on the same set of axes. The coordinates of the points at which the two lines intersect are the solutions to the system. What are Simultaneous Equations? Simultaneous equations are a set of equations that are solved at the same time.

Chinese Remainder Theorem Calculator
The Chinese remainder theorem is the name given to a system of congruences (multiple simultaneous modular equations ). The original problem is to calculate a number of elements which remainders (of their Euclidean division) are known.
