\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"%28x%2B60%29%2B%28x%2B10%29=180\"$ Start with the given equation.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x%2B60%2Bx%2B10=180\"$ Remove parenthesis.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2x%2B70=180\"$ Combine like terms on the left side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2x=180-70\"$ Subtract $\"70\"$ from both sides.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"2x=110\"$ Combine like terms on the right side.\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=%28110%29%2F%282%29\"$ Divide both sides by $\"2\"$ to isolate $\"x\"$ .\r
\n" ); document.write( "
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " $\"x=55\"$ Reduce.\r
\n" ); document.write( "
