Question

Solve the equation by error and trial method : z/3=4?​

Answer 1

Answer:

Step-by-step explanation:

error and trial method:

if z=9,then 9/3 =3 which is not equal to LHS

if z=15,then 15/3=5 which is not equal to LHS

if z=12,then 12/3=4,which is equal to LHS

THUS,z= is the correct solution

Answer 2

z=12.                                                Z/3=4x3/1x3.  = z/3=12/3.    = z=12
