The easiest way to solve for x in this case, is to first get rid of the decimals. To do this, multiply the entire equation by 10. Doing so will leave you with:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "85x + 80 = 13x + 150\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, we want to get all like terms on the same side of the equal sign. To do this, subtract 80 from both sides of the equal sign:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "85x + 80 - 80 = 13x + 150 - 80 =\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "85x = 13x + 70\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Now, subtract 13x from both sides of the equal sign:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "85x - 13x = 13x + 70 - 13x =\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "72x = 70\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Divide both sides of the equal sign by 72:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"72x%2F72+=+70%2F72\" =\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x+=+70%2F72\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "Finally, reduce the fraction to lowest terms to obtain your answer:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "\"x+=+35%2F36\"
\n" ); document.write( "
\n" );
