Let x = the amount before taxes.
\n" ); document.write( " $\"x%2B0.07x+=+462.24\"$ Simplify the left side.
\n" ); document.write( " $\"1.07x+=+462.24\"$ Divide both sides by 1.07
\n" ); document.write( " $\"x+=+432\"$
\n" ); document.write( "The cost before the tax is $432.00
\n" ); document.write( "The sales tax is 7% of $432.00 = 0.07($432) = $30.24
\n" ); document.write( "Check:
\n" ); document.write( " $\"x%2B0.07x+=+462.24\"$ Substitute x = $432.00
\n" ); document.write( " $\"432%2B0.07%28432%29+=+462.24\"$
\n" ); document.write( " $\"432%2B30.24+=+462.24\"$
\n" ); document.write( " $\"462.24+=+462.24\"$ OK! \n" ); document.write( "
