You can put this solution on YOUR website!
1 x -9 y = 8 .............1
\n" ); document.write( "
\n" ); document.write( "3 x + 1 y = -60 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by 9
\n" ); document.write( "1 x -9 y = 8
\n" ); document.write( "27 x + 9 y = -540
\n" ); document.write( "Add the two equations
\n" ); document.write( "28 x = -532
\n" ); document.write( "/ 28
\n" ); document.write( "x = -19
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x -9 y = 8
\n" ); document.write( "-19 -9 y = 8
\n" ); document.write( " -9 y = 8 + 19
\n" ); document.write( " -9 y = 27
\n" ); document.write( " y = -3 1
\n" ); document.write( "x= -19
\n" ); document.write( "y= -3
