如何在Laravel中解决此数据更新错误

I want to Update a Registration Form data. So , at first I have created a Table for the show data. In this table , I have included an ViewForUpdate button and I have passed the Id. When I click that ViewForUpdate button , it shows unique data correctly in an another page. After I inputted new data and when I click update button , it shows this error - 

MethodNotAllowedHttpException

So , How to fix this ??

Here is the RegViewUpdate.blade.php file

<html>
<head>

<body>

<form action="edit{{$users[0]->id}}" method="post" enctype="multipart/form-data">

{{ method_field('PUT') }}
{{ csrf_field() }}

<div class="form-group">
    <label>Name : *</label>
    <input type="text" class="form-control" name="name" value="{{$users[0]->name}}" required>
  </div>

  <div class="form-group">
    <label>Username : *</label>
    <input type="text" class="form-control" name="username" value="{{$users[0]->username}}" required>
  </div>

  <div class="form-group">
    <label>Password : *</label>
    <input type="password" class="form-control" name="password" value="{{$users[0]->pw}}" required>
  </div>

  <div class="form-group">
    <label>Upload Profile Picture :</label>
    <input type="file" class="form-control-file" name="file_img" aria-describedby="fileHelp">
    <small id="fileHelp" class="form-text text-muted">If U Want , U Can Skip Upload A Profile Picture</small>
  </div>

  <input type="submit" class="btn btn-primary" name="submit" value="Update">

</form>

</body>
</html>

Here is the RegViewController.php file

<?php

namespace App\Http\Controllers;

use Illuminate\Http\Request;
use DB;

class RegViewController extends Controller
{

    public function index()
    {
        return view('RegView');
    }

    public function show($id) {
        $users = DB::select('select * from academic where id = ?',[$id]);
        return view('RegViewUpdate',['users'=>$users]);
    }

    public function edit(Request $request, $id)
    {
        $name = $request->input('name');

        DB::update('update academic set name = ? where id = ?',[$name,$id]);
        echo "Record updated successfully.<br/>";

    }

}

Here is the Routes that I have created.

Route::get('edit/{id}','RegViewController@show');
Route::post('edit{id}','RegViewController@edit');
