Hi there,
\n" ); document.write( "Make the unknown number = x
\n" ); document.write( "If 10 be added to four time a certain number
\n" ); document.write( "10 + 4x
\n" ); document.write( "the result is 5 less than five times the number
\n" ); document.write( "5x - 5
\n" ); document.write( "........
\n" ); document.write( "10 + 4x = 5x - 5
\n" ); document.write( "Collect like terms
\n" ); document.write( "4x - 5x = -5 -10
\n" ); document.write( "-x = -15
\n" ); document.write( "x = 15
\n" ); document.write( "Unknown number = 15
\n" ); document.write( "Proof:
\n" ); document.write( "10 + 4x = 5x - 5
\n" ); document.write( "10 + 4(15) = 5(15) - 5
\n" ); document.write( "10 + 60 = 75 - 5
\n" ); document.write( "70 = 70
\n" ); document.write( "Hope this helps :-)
\n" ); document.write( "
\n" );
