B is the midpoint of segment AC. if BC=2x-15 and AC=x+9, find x
\n" ); document.write( "----------------
\n" ); document.write( "Draw the picture: A......B......C
\n" ); document.write( "Mark the segments: AC = x+9 ; BC = 2x-15
\n" ); document.write( "-------------------------
\n" ); document.write( "EQUATION:
\n" ); document.write( "BC is (1/2)AC
\n" ); document.write( "2x-15 = (1/2)(x+9)
\n" ); document.write( "4x-30 = x+9
\n" ); document.write( "3x = 39
\n" ); document.write( "x = 13
