Question

What should be the value of x so as to make 5x18 divisible by 9?

Answer 1

Answer:

x value is 4 sot that it is divisible by 9 and answer is 602

Answer 2

5+x+18=9

23+x=9

x= 9-23

x=-14

not possible

x+23=18

x=18-23

x=-5

not possible

x+23=27

x=27-23

x=4

possible

x+23=36

x=36-23

x=13

not possible

so the possible outcomes is 5

checking

5+4+18=27=27/9=3

hence proved that the value of x=4
