\n" ); document.write( " $\"y+=+0.08x\"$ .........eq.1
\n" ); document.write( " $\"y+=+100+%2B+0.04x\"$ .........eq.2
\n" ); document.write( "------------------\r
\n" ); document.write( "\n" ); document.write( " $\"y+=+100+%2B+0.04x\"$ .........eq.2 substitute $\"+0.08x\"$ for $\"y+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+0.08x+=+100+%2B+0.04x\"$ ....solve for $\"x\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+0.08x+-0.04x=+100+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+0.04x=+100+\"$ ....multiply both sides by $\"100\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+4x=+10000+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+x=+10000%2F4+\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"+highlight%28x=+2500%29\"$ \r
\n" ); document.write( "\n" ); document.write( "go to $\"y+=+0.08x\"$ .........eq.1 substitute $\"+2500\"$ for $\"x+\"$ and solve for $\"y\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"y+=+0.08%2A2500\"$ \r
\n" ); document.write( "\n" ); document.write( " $\"highlight%28y+=+200%29\"$ \r
