You can put this solution on YOUR website!
$\"y+=+-x+%2B5\"$
\n" ); document.write( " $\"y+=+2x+-+4\"$
\n" ); document.write( "One way to solve it is to use substitution. Set the 2 y's equal to each other.
\n" ); document.write( " $\"-x%2B5=2x-4\"$
\n" ); document.write( " $\"-x%2Bx%2B5=x%2B2x-4\"$
\n" ); document.write( " $\"5=3x-4\"$
\n" ); document.write( " $\"5%2B4=3x-4%2B4\"$
\n" ); document.write( " $\"9=3x\"$
\n" ); document.write( " $\"9%2F3=3x%2F3\"$
\n" ); document.write( " $\"3=x\"$
\n" ); document.write( "Now let x=3 in one of the equations and solve for y:
\n" ); document.write( " $\"y=-3%2B5\"$
\n" ); document.write( " $\"y=2\"$
\n" ); document.write( "The solution, (x,y)=(3,2)
