\n" ); document.write( "Let $\"x=number\"$
\n" ); document.write( "1st condition: $\"7x\"$ , seven times the number
\n" ); document.write( "2nd condition: $\"2x\"$ , twice the number
\n" ); document.write( "3rd condition ---> ADD = 63 --- $\"system%287x%2C2x%2C63%29\"$
\n" ); document.write( "Continuing,
\n" ); document.write( " $\"7x%2B2x=63\"$
\n" ); document.write( " $\"9x=63\"$ ------> $\"cross%289%29x%2Fcross%289%29=cross%2863%297%2Fcross%289%29\"$
\n" ); document.write( " $\"x=7\"$ ANSWER
\n" ); document.write( "Check via the 3 conditions ----> $\"7%2A7=49\"$ , $\"2%2A7=14\"$ ---Addition, 49+14=63
