3x-2y=-1 multiply by -2
\n" ); document.write( "2x-3y=-4 multiply by 3 & add
\n" ); document.write( "-6x+4y=2
\n" ); document.write( "6x^2-9y=-12
\n" ); document.write( "-----------------
\n" ); document.write( "-5y=-10
\n" ); document.write( "y=-10/-5
\n" ); document.write( "y=2 ans.
\n" ); document.write( "3x-2*2=-1
\n" ); document.write( "3x-4=-1
\n" ); document.write( "3x=-1+4
\n" ); document.write( "3x=3
\n" ); document.write( "x=1 ans.
\n" ); document.write( "Proof:
\n" ); document.write( "2*1-3*2=-4
\n" ); document.write( "2-6=-4
\n" ); document.write( "-4=-4 \n" ); document.write( "
