4x-3y=12 now multiply the second equation by -4 & add them:
\n" ); document.write( "-4x-8y=-56
\n" ); document.write( "--------------------------------------
\n" ); document.write( "-11y=-44
\n" ); document.write( "y=-44/-11
\n" ); document.write( "y=4 answer. now substitute 4 for y & solve for x thus:
\n" ); document.write( "x+2*4=14
\n" ); document.write( "x+8=14
\n" ); document.write( "x=14-8
\n" ); document.write( "x=6 answer.
\n" ); document.write( "proof
\n" ); document.write( "4*6-3*4=12
\n" ); document.write( "24-12=12
\n" ); document.write( "12=12 \n" ); document.write( "
