there is no formula?

Answer 8

from here :
z = 13a + 5 = 18b + 3
we should use hit & trial method?

Answer 9

z=13x+5

z=18p+3

=> 13x=(z-5)
18p=(z-3)

Answer 10

from here i used hit & trial method

Answer 11

can u explain me how is it?

Answer 12

13*3=39
18*2=36

these 2 multiples do not satisfies the equations

13*4=52
18*3=54

these 2 multiples satisfies the equations i made.

The rule i used in choosing these certain multiples is tht there should not be any large difference between the multiples.
