Question

pick out the solutions of the equation 3x - 5 = 19 from the values 5,3,8,11. show that the other values do not satisfy the equation.​

Answer 1

8 is the right answer

let take 3

=3 (3)-5

=9-5

=4

other 11

=3 (11)-5

=33-5

28

other 5

=3 (5)-5

=15-5

=10

so above are not satisfied for given given equation

but

8 is satisfied

=3 (8)-5

=24-5

=19
