You can put this solution on YOUR website!
Assume the problems are (x is not part of the denominator)
\n" ); document.write( "\"%282%2F3%29x\" = 36
\n" ); document.write( "Multiply both sides by 3 to get rid of the denominator
\n" ); document.write( "2x = 3(36)
\n" ); document.write( "2x = 108
\n" ); document.write( "x = \"108%2F2\"
\n" ); document.write( "x = 54
\n" ); document.write( ":
\n" ); document.write( "Check solution by substituting 54 for x in the original equation
\n" ); document.write( "\"%282%2F3%29%2A54\" = 36
\n" ); document.write( "3 cancels into 54,
\n" ); document.write( "2(18) = 36
\n" ); document.write( ";
\n" ); document.write( ":
\n" ); document.write( "\"%285%2F9%29x\" = \"7%2F18\"
\n" ); document.write( "Multiplying by 18 will clear the denominators here
\n" ); document.write( "2(5)x = 7
\n" ); document.write( "10x = 7
\n" ); document.write( "x = \"7%2F10\"
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solution
\n" ); document.write( "\"%285%2F9%29%2A%287%2F10%29\" = \"7%2F18\"
\n" ); document.write( "Cancel 5 into 10
\n" ); document.write( "\"%281%2F9%29%2A%287%2F2%29\" = \"7%2F18\"
\n" ); document.write( "
\n" );
