how do you solve these problems?
\n" ); document.write( "\"180%28n-2%29%2Fn=108\"
\n" ); document.write( "\"180%28n-2%29%2Fn=120\"
\n" ); document.write( "\"180%28n-2%29%2Fn=150\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Steps:
\n" ); document.write( "1. Multiply by 2 on both sides of the equation to get rid of the fraction.
\n" ); document.write( "2. Mulitply 180 by each term inside the parenthesis.
\n" ); document.write( "3. Move all n terms on the left, and integers on the right.
\n" ); document.write( "4. Combine like terms.
\n" ); document.write( "5. Divide by coefficient of variable on both sides to find the value of n.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Here's the first one. I'll let you do the other two as they're very similar.
\n" ); document.write( "\"180%28n-2%29%2Fn=108\"
\n" ); document.write( "\"180n-360=108n\"
\n" ); document.write( "\"180n-108n=360\"
\n" ); document.write( "\"72n=360\"
\n" ); document.write( "\"n=360%2F72\"
\n" ); document.write( "\"n=5\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Done with the first one!
\n" ); document.write( "
