Multiply the top equation by 2: 12x + 6y = 102.
\n" ); document.write( "Add corresponding sides with the bottom equation: 2x-6y = 38;
\n" ); document.write( "14x = 140, or x = 10.
\n" ); document.write( "Then multiply the bottom eqn by -3: -6x+18y = -114.
\n" ); document.write( "Addc corresponding sides with the top equation: 6x + 3y = 51.
\n" ); document.write( "21y = -63, or y = -3.
\n" ); document.write( "
