Cross multiply! :-D
\n" ); document.write( " $\"-15%2Fx+=+-21%2Fx-2\"$
\n" ); document.write( "This gives us:
\n" ); document.write( " $\"-15%2A%28x-2%29=-21%2Ax\"$
\n" ); document.write( "Distribute the -15:
\n" ); document.write( " $\"-15x%2B30=-21x\"$
\n" ); document.write( "Move the -15x to the other side:
\n" ); document.write( " $\"30=-6x\"$
\n" ); document.write( "Divide both sides by -6:
\n" ); document.write( " $\"x=-5\"$
\n" ); document.write( "Yay! \n" ); document.write( "
