$\"4%5E%282x%2B4%29=16%5E%283x%2B6%29\"$
\n" ); document.write( ":
\n" ); document.write( "We also write 16 as 4^2 so we have:
\n" ); document.write( " $\"4%5E%282x%2B4%29=4%5E%282%283x%2B6%29%29\"$
\n" ); document.write( ":
\n" ); document.write( " $\"4%5E%282x%2B4%29=4%5E%286x%2B12%29\"$
\n" ); document.write( "therefore:
\n" ); document.write( "2x + 4 = 6x + 12
\n" ); document.write( ":
\n" ); document.write( "4 - 12 = 6x - 2x
\n" ); document.write( ":
\n" ); document.write( "-8 = 4x
\n" ); document.write( ":
\n" ); document.write( "x = -8/4
\n" ); document.write( ":
\n" ); document.write( "x = -2
