Let the amount Jake withdrew from the bank be represented by x. Therefore, Jake started with $8, withdrew x dollars, and then added that amount to his wallet. This can be represented as 8 + x = 83. Solving for x, we find that x = 75. Therefore, Jake withdrew $75 from the bank.
Some day my prints will come.
As it is, PHP does not have a preprocessor; it is a preprocessor that processes form variables and other environmental variables and prints HTML or general text.
I believe the best way is to show you an example: class Car{ private $gas=0; private __construct(){ $gas=500; //when you create an object your gas tank is automatically filled with 500 gas for a start } public function fill_the_tank($amount){ $gas=$amoung; } public function get_gas(){ return $gas; } } $ferrari = new Car; echo $ferrari->get_gas(); //prints out "500" $ferrari->get_gas(); //prints out nothing, but also doesn't end up in error $ferrari->fill_the_tank(100); echo $ferrari->get_gas() //prints out "600"
