lilly had 750 and elise had 215.
\n" ); document.write( "their mom gave them x allowance each.
\n" ); document.write( "after that, lilly had twice as much as elise.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "750 + x = 2 * (215 + x)
\n" ); document.write( "simplify to get 750 + x = 430 + 2 * x
\n" ); document.write( "subtract 430 from both sides of the equation and subtract x from both sides of the equation to get 750 - 430 = 2x - x
\n" ); document.write( "simplify to get 320 = x\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "the allowance was 320.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "after the allowance, .....\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "lilly had 750 + 320 = 1070.
\n" ); document.write( "elise has 215 + 320 = 535.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "1070 is two times 535 which means the solution is good.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solution is their mom gave them 320 each.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
