You can put this solution on YOUR website!
1. 200= 210/(1+x)
\n" ); document.write( "step 1 - multiply by 1+x to get
\n" ); document.write( " $\"200%281%2Bx%29+=+210\"$
\n" ); document.write( "distribute to get
\n" ); document.write( " $\"200+%2B+200x+%2B+210\"$
\n" ); document.write( "subtract to get
\n" ); document.write( " $\"200x+=+10\"$
\n" ); document.write( "divide to get
\n" ); document.write( " $\"x+=+1%2F20\"$
\n" ); document.write( "-----
\n" ); document.write( "2. 110.00 = 133.10/(1+x)^2
\n" ); document.write( "step 1 - multiply by (1+x)^2 to get
\n" ); document.write( " $\"110%281%2Bx%29%5E2+=+133.10\"$
\n" ); document.write( "step 2- divide by 110 to get
\n" ); document.write( " $\"%281%2Bx%29%5E2+=+1.21\"$
\n" ); document.write( "square root both sides to get
\n" ); document.write( " $\"1%2Bx+=+%2B-1.1\"$
\n" ); document.write( "subtract 1 to get
\n" ); document.write( " $\"x+=+-1+%2B-+1.1\"$
\n" ); document.write( "so,
\n" ); document.write( "x = -.1
\n" ); document.write( "or
\n" ); document.write( "x = -2.1
\n" ); document.write( "-----
\n" ); document.write( "3. 0.08243=〖[1+x/4]〗4 - 1
\n" ); document.write( "--> not sure what we have on this one :((
\n" ); document.write( "----
\n" ); document.write( "4. 34.99=100e^x
\n" ); document.write( "step 1 - divide by 100 to get
\n" ); document.write( " $\".3499+=+e%5Ex\"$
\n" ); document.write( "step 2 - ln both sides to get
\n" ); document.write( " $\"x+=+-1.05010\"$ \n" ); document.write( "

\n" );
