Use log property: \n" ); document.write( " \n" ); document.write( "Rewrite equation in exponential form, Or notice that if log(a)=log(b) then a=b \n" ); document.write( " \n" ); document.write( "Multiply by (x-4) on both sides \n" ); document.write( " \n" ); document.write( "Distribute \n" ); document.write( " \n" ); document.write( "Subtract 3x on both sides \n" ); document.write( " \n" ); document.write( "Subtract 4 on both sides \n" ); document.write( " \n" ); document.write( "Divide by -2 on both sides \n" ); document.write( " |
