Three boxes of gaming machines and five boxes of DVDs weight 72 pounds. How much does each box weigh? Now I got put this in a these following steps
\n" ); document.write( "To write a system of equations follow these steps.
\n" ); document.write( "Step 1. Read the problem carefully.
\n" ); document.write( "Step 2. Identify key words and draw a picture to help you visualize the problem.
\n" ); document.write( "Step 3. Define two unknown variables.
\n" ); document.write( "Step 4. Write a system of equations.
\n" ); document.write( "Then I have use substitution and/or addition to figure it out I know I have to use x = Boxes of DVD's y = gaming machine boxes
\n" ); document.write( "x + 3y = 48 and 5x + 3y = 72 now this gets tricky
\n" ); document.write( "3(x + 3y) = 48
\n" ); document.write( "3x + 3y = 48
\n" ); document.write( "But this does not look right What am I doing wrong\r

\n" ); document.write( "

\r\n" );
document.write( "3x +  y = 48     (1)    (x is the weight of the box of gaming machines)\r\n" );
document.write( "3x + 5y = 72     (2)    (y is the weight of the box of DVDs)\r\n" );
document.write( "-------------------------\r\n" );
document.write( "\r\n" );
document.write( "Subtract equation (1) from equation (2) (both sides). You will get\r\n" );
document.write( "\r\n" );
document.write( "4y = 72 - 48 = 24  ====>  y =  = 6.\r\n" );
document.write( "\r\n" );
document.write( "Thus the the weight of the box of DVDs is 6 pounds.\r\n" );
document.write( "\r\n" );
document.write( "\r\n" );
document.write( "From this point, can you complete the solution on your own ?\r\n" );
