Using the addition method solve the equation
\n" ); document.write( "2x-7y=4
\n" ); document.write( "5x-5y=4
\n" ); document.write( "------
\n" ); document.write( "Modify for elimination:
\n" ); document.write( "10x - 35y = 20
\n" ); document.write( "-10x + 10y = -8
\n" ); document.write( "--------
\n" ); document.write( "Add and solve for \"y\":
\n" ); document.write( "-25y = 12
\n" ); document.write( "y = -12/25
\n" ); document.write( "------
\n" ); document.write( "Solve for \"x\":
\n" ); document.write( "5x - 5(-12/25) = 4
\n" ); document.write( "5x + (60/25) = 4
\n" ); document.write( "5x = 40/25
\n" ); document.write( "x = 8/25
