Three numbers: a, b, c
\n" ); document.write( ":
\n" ); document.write( " are such that the second is six less than three times the first,
\n" ); document.write( "b = 3a - 6
\n" ); document.write( "or
\n" ); document.write( "3a = b + 6
\n" ); document.write( "divide by 3
\n" ); document.write( "a = \"1%2F3\"b + 2
\n" ); document.write( ":
\n" ); document.write( "and the third is two more than two-thirds of the second.
\n" ); document.write( "c = \"2%2F3\"b + 2
\n" ); document.write( ":
\n" ); document.write( "If the sum of the numbers is 172,
\n" ); document.write( "a + b + c = 172
\n" ); document.write( "Replace a, and c
\n" ); document.write( "(\"1%2F3\"b + 2) + b + (\"2%2F3\"b + 2) = 172
\n" ); document.write( "Combine like terms
\n" ); document.write( "2b + 4 = 172
\n" ); document.write( "2b = 172 - 4
\n" ); document.write( "2b = 168
\n" ); document.write( "b = 168/2
\n" ); document.write( "b = 84 is the 2nd number
\n" ); document.write( "then
\n" ); document.write( "a = \"1%2F3\"(84) + 2
\n" ); document.write( "a = 28 + 2
\n" ); document.write( "a = 30 is the 1st number
\n" ); document.write( "and
\n" ); document.write( "c = \"2%2F3\"(84) + 2
\n" ); document.write( "c = 56 + 2
\n" ); document.write( "c = 58
\n" ); document.write( ":
\n" ); document.write( "Check: 30 + 84 + 58 = 172
\n" ); document.write( ":
\n" ); document.write( "find the smallest number. 30
\n" ); document.write( "
\n" );
