\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "let x = the number of hours that yvonne worked.
\n" ); document.write( "let y = the number of hours that peter worked.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you get x = 3/4 * y
\n" ); document.write( "y - x = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "those are your two equations that you want to solve simultaneously.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "replace x with 3/4 * y in the second equation to get:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y - 3/4 * y = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "combine like terms to get 1/4 * y = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for y to get y = 80.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "in the equation of y - x = 20, replace y with 80 to get 80 - x = 20 and solve for x to get x = 60.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you get y = 80 and x = 60\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "y is the number of hours that peter worked.
\n" ); document.write( "x is the number of hours that yvonne worked.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "x = 3/4 * y
\n" ); document.write( "y - x = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the requirements of the problem were satisfied and that's your solution.\r
