y=5x -126 when x is 3 times as great as y What is the value of x
\n" ); document.write( ".
\n" ); document.write( "From:\"x is 3 times as great as y\" we have:
\n" ); document.write( "x = 3y
\n" ); document.write( "solving for y we get:
\n" ); document.write( "x/3 = y
\n" ); document.write( ".
\n" ); document.write( "substitute the above into:
\n" ); document.write( "y=5x -126
\n" ); document.write( "x/3 = 5x -126
\n" ); document.write( "multiplying both sides by 3:
\n" ); document.write( "x = 15x -378
\n" ); document.write( "-14x = -378
\n" ); document.write( "x = -378/(-14)
\n" ); document.write( "x = 27
\n" ); document.write( " \n" ); document.write( "
\n" );
