I have tried and got some of them but these two I can not seem to get. If you can show me step by step how to do these that would help a ton and thank you in advance. Ok so my question is:
\n" ); document.write( "y= u+1/u+2 solve for u
\n" ); document.write( "and the other one i did not get is:
\n" ); document.write( "ax+b=cx+d solve for x

Well I am glad you asked this because these problems a little challenging. The problem is I'm not sure how to explain how to do this...so i'm just going to take you step by step through the process.\r
\n" ); document.write( "\n" ); document.write( "\"y+=+%28u%2B1%29%2F%28u%2B2%29\"
\n" ); document.write( "First we multiply both sides by (u+2) and get
\n" ); document.write( "\"y%28u%2B2%29+=+%28u%2B1%29\"
\n" ); document.write( "Now we subtract u from both sides.
\n" ); document.write( "\"y%28u%2B2%29-u+=+1\"
\n" ); document.write( "Next we distribute the y.
\n" ); document.write( "\"yu%2B2y-u+=+1\"
\n" ); document.write( "Rearrainging a little we get:
\n" ); document.write( "\"yu-u%2B2y+=+1\"
\n" ); document.write( "now we factor out a u.
\n" ); document.write( "\"u%28y-1%29%2B2y+=+1\"
\n" ); document.write( "subtract 2y from both sides.
\n" ); document.write( "\"u%28y-1%29+=+1-2y\"
\n" ); document.write( "Now we divide both sides by y-1.
\n" ); document.write( "\"u+=+%281-2y%29%2F%28y-1%29\"
\r
\n" ); document.write( "\n" ); document.write( "The next problem is somewhat similar to the problem above. First we subtract cx from both sides:
\n" ); document.write( "\"ax%2Bb-cx=d\"
\n" ); document.write( "Next we rearrange a little
\n" ); document.write( "\"ax-cx%2Bb=d\"
\n" ); document.write( "Subtract b from both sides
\n" ); document.write( "\"ax-cx=d-b\"
\n" ); document.write( "Factor out an x
\n" ); document.write( "\"x%28a-c%29=d-b\"
\n" ); document.write( "And divide by a-c
\n" ); document.write( "\"x+=+%28d-b%29%2F%28a-c%29\"
\n" ); document.write( "
\n" );
