One number is 12 more than another. The sum of the smaller number and twice the larger number is 39. Find the larger number.
\n" ); document.write( "5
\n" ); document.write( "7
\n" ); document.write( "17
\n" ); document.write( "34\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Let x: smaller number
\n" ); document.write( " x+12: larger number\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Equation: x + 2(x+12) = 39
\n" ); document.write( " x + 2x + 24 = 39
\n" ); document.write( " 3x + 24 = 39
\n" ); document.write( " 3x = 39 - 24
\n" ); document.write( " 3x = 15
\n" ); document.write( " 3x/3 = 15/3
\n" ); document.write( " x = 5\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Larger number: x + 12
\n" ); document.write( " 5 + 12
