You can put this solution on YOUR website!
x + y + z = 4
\n" ); document.write( "-(4x + y − 3z = 3)
\n" ); document.write( "-3x + 4z = 1
\n" ); document.write( ".....
\n" ); document.write( "2x − 3y + 2z = −2
\n" ); document.write( "x + y + z = 4 |multiplying thru by 3 to eliminate the x variable by adding the Eqs
\n" ); document.write( "5x + 5z = 10
\n" ); document.write( "x + z = 2 |multiplying thru by 3 to eliminate the x variable by adding the Eqs
\n" ); document.write( "-3x + 4z = 1
\n" ); document.write( "7z = 7
\n" ); document.write( "z = 1
\n" ); document.write( "will Let You finish it Up finding ordered triple (1, 2, 1)
