a) Solve for x:
\n" ); document.write( "\"-x%2B12+=+-4%2Bx\" Add x to both sides of the equation.
\n" ); document.write( "\"12+=+-4%2B2x\" Add 4 to both sides.
\n" ); document.write( "\"16+=+2x\" Divide both sides by 2.
\n" ); document.write( "\"8+=+x\" or \"x+=+8\"
\n" ); document.write( "b) Solve for x:
\n" ); document.write( "\"3%28x-2%29%2B2+=+2%28x-4%29\" Apply the distributive property to both sides.
\n" ); document.write( "\"3x-6%2B2+=+2x-8\" Combine like-terms.
\n" ); document.write( "\"3x-4+=+2x-8\" Subtract 2x from both sides.
\n" ); document.write( "\"x-4+=+-8\" Add 4 to both sides.
\n" ); document.write( "\"x+=+-4\"
\n" ); document.write( "c) Solve for x:
\n" ); document.write( "\"x%2F5+-+x%2F3+=+8%2F15\" Combine (subtract) the fractions on the left side.
\n" ); document.write( "\"%283x-5x%29%2F15+=+8%2F15\" Simplify.
\n" ); document.write( "\"%28-2x%29%2F15+=+8%2F15\" Multiply both sides by 15.
\n" ); document.write( "\"-2x+=+8\" Divide both sides by -2.
\n" ); document.write( "\"x+=+-4\"\r
\n" ); document.write( "\n" ); document.write( "d) Solve for r:
\n" ); document.write( "\"I+=+Prt\" Divide both sides by Pt
\n" ); document.write( "\"I%2FPt+=+r\" or \"r+=+I%2FPt\"
\n" ); document.write( "
\n" );
