a) \"7x+-+10+=+12\"\r
\n" ); document.write( "\n" ); document.write( "b) \"3x+=+9x+-+15\"\r
\n" ); document.write( "\n" ); document.write( "c) \"4%28x+-+9%29+=+%28x+-+5%29+%2B+9\"\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For part a:\r
\n" ); document.write( "\n" ); document.write( "a) \"7x+-+10+=+12\"
\n" ); document.write( "\"7x+=+22\" add 10 on both sides
\n" ); document.write( "\"highlight%28x+=+22%2F7%29\" divide 7 on both sides\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "For part b:
\n" ); document.write( "b) \"3x+=+9x+-+15\"
\n" ); document.write( "\"-6x+=+-15\" subtract 9x on both sides
\n" ); document.write( "\"highlight%28x+=+5%2F2%29\" divide both sides by -6 and simplify\r
\n" ); document.write( "\n" ); document.write( "For part c:
\n" ); document.write( "c) \"4%28x+-+9%29+=+%28x+-+5%29+%2B+9\"
\n" ); document.write( "\"4x+-+36%29+=+x+%2B+4+\" combine like terms and distribute
\n" ); document.write( "\"3x+=+40\" subtract x on both sides and add 36 on both sides
\n" ); document.write( "\"highlight%28x+=+40%2F3%29\" divide 3 on both sides\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "
