Three numbers: a, b, c
\n" ); document.write( "write an equation for each statement
\n" ); document.write( "\"The sum of three numbers is 145.\"
\n" ); document.write( "a + b + c = 145
\n" ); document.write( " The third number is 4 times more the second number.
\n" ); document.write( "c = 4b
\n" ); document.write( " The first number is 7 more than the second.
\n" ); document.write( "a = b + 7
\n" ); document.write( ":
\n" ); document.write( "In the first equation, replace a with (b+7); replace c with 4b
\n" ); document.write( "(b+7) + b + 4b = 145
\n" ); document.write( "6b = 145 - 7
\n" ); document.write( "6b = 138
\n" ); document.write( "b = 138/6
\n" ); document.write( "b = 23
\n" ); document.write( "then
\n" ); document.write( "a = 23 + 7
\n" ); document.write( "a = 30
\n" ); document.write( "and
\n" ); document.write( "c = 4(23)
\n" ); document.write( "c = 92
\n" ); document.write( ";
\n" ); document.write( ";
\n" ); document.write( "Check this
\n" ); document.write( "30 + 23 + 92 = 145 \n" ); document.write( "
\n" );
