Given:
\n" ); document.write( ".
\n" ); document.write( "2(n-7)+3=9
\n" ); document.write( ".
\n" ); document.write( "First do the distributive multiplication on the left side by multiplying 2 times each of
\n" ); document.write( "the terms inside the parentheses to get:
\n" ); document.write( ".
\n" ); document.write( " $\"2n+-+14+%2B+3+=+9\"$
\n" ); document.write( ".
\n" ); document.write( "Next add the -14 and the + 3 on the left side to get:
\n" ); document.write( ".
\n" ); document.write( " $\"2n+-+11+=+9\"$
\n" ); document.write( ".
\n" ); document.write( "Then add 11 to both sides to eliminate the 11 on the left side and get:
\n" ); document.write( ".
\n" ); document.write( " $\"2n+=+20\"$
\n" ); document.write( ".
\n" ); document.write( "Finally divide both sides by 2 to get the solution:
\n" ); document.write( ".
\n" ); document.write( " $\"n+=+20%2F2+=+10\"$
\n" ); document.write( ".
\n" ); document.write( "Substitute 10 for n in the original equation to check the answer:
\n" ); document.write( ".
\n" ); document.write( " $\"2%28n-7%29%2B3=9\"$
\n" ); document.write( ".
\n" ); document.write( " $\"2%2810-7%29+%2B+3+=+9\"$
\n" ); document.write( ".
\n" ); document.write( " $\"+2%283%29+%2B3+=+9\"$
\n" ); document.write( ".
\n" ); document.write( " $\"6+%2B+3+=+9\"$
\n" ); document.write( ".
\n" ); document.write( "It checks! So our answer is correct.
\n" ); document.write( ".
\n" ); document.write( "Hope this helps you see ways in which you can solve basic math equations. \n" ); document.write( "
