4x+10=13x-8
\n" ); document.write( "our goal is to isolate x
\n" ); document.write( "subtract 10 from both sides
\n" ); document.write( "4x+10-10=13x-8-10
\n" ); document.write( "4x=13x-18
\n" ); document.write( "subtract 13x from both sides
\n" ); document.write( "4x-13x=-18
\n" ); document.write( "-9x=-18
\n" ); document.write( "we want x to be positive so mutiply both sides by \"-\"
\n" ); document.write( "-(-9x)=-(-18)
\n" ); document.write( "9x=18
\n" ); document.write( "divide both sides by 9
\n" ); document.write( "9x/9=18/9
\n" ); document.write( "x=2
\n" ); document.write( "
\n" );
