Question

trial and error method solve by same equation​

Answer 1

Hi,

here u go with ur answer..

Substituting different values of the variable and checking the equality of LHS and RHS is the trial and error method. Let us solve the equation 3x + 5 = 17. We start to substitute different values of x. The value for which both the sides are balanced is the required solution.

Answer 2

Trial and error is a fundamental method of problem-solving. It is characterized by repeated, varied attempts which are continued until success, or until the practicer stops trying.

Trial and error refers to the process of verifying that a certain choice is right (or wrong). We simply substitute that choice into the problem and check. Some questions can only be solved by trial and error; for others we must first decide if there isn't a faster way to arrive at the answer.
