one number is 5 times as large as another number and the sum is 78

\n" ); document.write( "\n" ); document.write( "From the information given, you know that:
\n" ); document.write( " $\"78=x%2By\"$

\r
\n" ); document.write( "\n" ); document.write( "And, that 5x takes the place of y:
\n" ); document.write( " $\"78=x%2B5x\"$

\r
\n" ); document.write( "\n" ); document.write( "Add:
\n" ); document.write( " $\"78=6x\"$

\r
\n" ); document.write( "\n" ); document.write( "Divide both sides by 6:
\n" ); document.write( " $\"13=x\"$

\r
\n" ); document.write( "\n" ); document.write( "And because y=5x:
\n" ); document.write( " $\"y=5%2813%29\"$

\r
\n" ); document.write( "\n" ); document.write( "Multiply:
\n" ); document.write( " $\"y=65\"$

\r
\n" ); document.write( "\n" ); document.write( "So, you know that x=13 and y=65. To check, add the two, and they should equal 78.
\n" ); document.write( " $\"78=13%2B65\"$
