At the same time, Maria was 6x years old.\r \n" ); document.write( "\n" ); document.write( "At the present time, Kate will be x + 4 years old and Maria will be 6x + 4 years old. We are told that Maria is now four times as old as Kate. So we have the following equation to solve.\r \n" ); document.write( "\n" ); document.write( " 6x + 4 = 4(x + 4) \n" ); document.write( " 6x - 2x = 16 - 4 \n" ); document.write( " 2x = 12 \n" ); document.write( " x = 6\r \n" ); document.write( "\n" ); document.write( "So Kate is now 6 + 4 = 10 years old and Maria is now 6(6) + 4 = 40 years old. \n" ); document.write( " \n" ); document.write( " |
