You can put this solution on YOUR website!
x = what she earned last week.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this week she earned 220.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this is equal to 12 less than twice what she earned last week.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "220 = 2 * x - 12 is your equation.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for x to get x = (220 + 12) / 2 = 232 / 2 = 116.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "she earned 116 last week.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this week she earned 12 less than 2 times that.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "this week she earned 2 * 116 - 12 = 232 - 12 = 220.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "numbers check out so the solution appears to be good.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution is that she earned 116 last week.\r
