2x-2y=-8
\n" ); document.write( "2x+8=2y
\n" ); document.write( " $\"y=x%2B4\"$
\n" ); document.write( " $\"y=%28-1%2F2%29x-%281%2F2%29\"$
\n" ); document.write( "First graph the two lines:
\n" ); document.write( " $\"+graph%28+800%2C+800%2C+-10%2C+10%2C+-10%2C+10%2C+x%2B4%2C+-0.5x-0.5%29+\"$
\n" ); document.write( "The solution is the intersection: (-3,1)
\n" ); document.write( "To check plug these values in the original equations. \n" ); document.write( "
