1 x + 3 y = 11 .............1
\n" ); document.write( "
\n" ); document.write( "4 x + 1 y = 6 .............2
\n" ); document.write( "Eliminate y
\n" ); document.write( "multiply (1)by 1
\n" ); document.write( "Multiply (2) by -3
\n" ); document.write( "1 x 3 y = 11
\n" ); document.write( "-12 x -3 y = -18
\n" ); document.write( "Add the two equations
\n" ); document.write( "-11 x = -7
\n" ); document.write( "/ -11
\n" ); document.write( "x = 1
\n" ); document.write( "plug value of x in (1)
\n" ); document.write( "1 x + 3 y = 11
\n" ); document.write( "1 + 3 y = 11
\n" ); document.write( " 3 y = 11 -1
\n" ); document.write( " 3 y = 10
\n" ); document.write( " y = 3
\n" ); document.write( "x= 1
\n" ); document.write( "y= 3 \r
\n" ); document.write( "\n" ); document.write( "(1,3) is the solution.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "If (3,-6) is a solution then it must satisfiy both equations.
\n" ); document.write( "plug (3,-6) in one of the equations
\n" ); document.write( "x+3y=11\r
\n" ); document.write( "\n" ); document.write( "3+(-6)3=-15. \r
\n" ); document.write( "\n" ); document.write( "This is not equal to 11 hence (3,-6) is not the solution of this system
