Solve for x:
\n" ); document.write( " $\"2log%28%287%29%29%5Ex+=+4\"$ Divide both sides by 2.
\n" ); document.write( " $\"log%28%287%29%29%5Ex+=+2\"$ Apply the power rule for logarithms.
\n" ); document.write( " $\"xlog%287%29+=+2\"$ Divide both sides by log(7)
\n" ); document.write( " $\"x+=+2%2Flog%28%287%29%29\"$ Evaluate.
\n" ); document.write( " $\"x+=+2.366589\"$ \n" ); document.write( "
