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 = \n" ); document.write( ": \n" ); document.write( "and the third is two more than two-thirds of the second. \n" ); document.write( "c = \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( "( \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 = \n" ); document.write( "a = 28 + 2 \n" ); document.write( "a = 30 is the 1st number \n" ); document.write( "and \n" ); document.write( "c = \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( " |
