Question 1196693
.
Use two equations in two variables to solve the application
The salaries of the president and vice president of a certain country total $662,400 a year. 
If president makes 247,600 more than the vice president, find each salaries
~~~~~~~~~~~~~~~


<pre>   
    P + V = 662400

    P - V = 247600
--------------------------  Add the equations

    2P    = 662400 + 247600

    2P    = 910000

     P    = 910000/2 = 455000


    Then from the very first equation  

    V = 662400 - 455000 = 207400.


<U>ANSWER</U>.  P = $455000;   V = $207400.
