Enter a mod b statement

x ≡ (mod )
  

Solve the modulus equation

3x ≡ 7(mod 4)

Step 1: Calculate d = (3,4)

GCF (3,4) = 1

Step 2: We check to see if 1 | 7

7  =  7
  1

There will be 1 solutions mod 4

Build Diophantine equation from GCF

3x - 4y = 7

Final Answer

Extended Euclidean Algorithm
for 3 and 4
x = 1 and y = -1
