2(-5a+7)=-a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "First remove the parentheses by the distributive property:
\n" ); document.write( "-10a + 14 = -a\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Next, you need to get the variable terms on one side (in this case preferably the right side by adding 10a to each side!):\r
\n" ); document.write( "\n" ); document.write( " $\"-10a+%2B+10a+%2B+14+=+-1a+%2B+10a\"$
\n" ); document.write( " $\"14+=+9a\"$ \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Finally, divide both sides by 9:
\n" ); document.write( " $\"14%2F9+=+%289a%29%2F9+\"$
\n" ); document.write( " $\"14%2F9+=+a\"$ \r
