You can put this solution on YOUR website!
2n+5n=77 becomes 7n=77, which reduces to n=11 after dividing both sides by 7.
\n" ); document.write( " $\"5%2Bexpr%281%2F3%29n=2\"$ becomes 15+3n=6 after multiplying both sides by 3. Subtract 15 from sides to get 3n=-9, and divide both sides by 3 to get n=-3.
\n" ); document.write( " $\"9-expr%281%2F4%29n=6\"$ becomes 36-n=24 after multiplying both sides by 4. Subtract 36 from both sides to get -n=-12, which reduces to n=12.
\n" ); document.write( " $\"expr%281%2F8%29n%2B20=32\"$ becomes n+160=256 after multiplying both sides by 8. Subtracting 160 from sides gives us n=96.
