how to solve the answer ​

Answer 1

Answer:

x=2,8,14,20..........................

So 5x=10,40,70,100...........

Step-by-step explanation:

5x ≡ 4(mod6)

When 5x is divided by 6 then remainder is 4

so 5x=q*6+4

5x-4=6q

x=(6q+4)/5............(1)

x is an integer

6q+4 is divisible by by5

so q=1,6,11,16................

putting value of q in (1)

x=2,8,14,20..........................
