You can put this solution on YOUR website!
Solve the folowing system.
\n" ); document.write( "x - y = 1
\n" ); document.write( "x + y = 1
\n" ); document.write( "This is the elimination method, add the two equations and the y is eliminated.
\n" ); document.write( "x-y=1
\n" ); document.write( "x+y=1
\n" ); document.write( "______
\n" ); document.write( "2x+0=2
\n" ); document.write( "2x=2
\n" ); document.write( "2x/2=2/2
\n" ); document.write( "x=1
\n" ); document.write( "Substitute 1 in for x in either equation and solve for y.
\n" ); document.write( "1+y=1
\n" ); document.write( "-1+1+y=1-1
\n" ); document.write( "y=0
\n" ); document.write( "The solution (x,y)=(1,0)
