You can put this solution on YOUR website!
To get from $\"2x%2B1=15\"$ to $\"2x=14\"$ , you would subtract 1 from both sides of the first equation.\r
\n" ); document.write( "\n" ); document.write( "To find the value of x that makes these equations equivalent, in $\"2x+=+14\"$ , divide both sides by 2.\r
\n" ); document.write( "\n" ); document.write( " $\"2x+=+14\"$ Divide both sides by 2.
\n" ); document.write( " $\"x+=+7\"$ \r
\n" ); document.write( "\n" ); document.write( "You can check this yourself by substituting 7 for x in each equation. \n" ); document.write( "
