Algebra.Com's Answer #266080 by robertb(5830)![]() ![]() You can put this solution on YOUR website! Multiply the top eqn by 2, with the purpose of eliminating y: 12x - 2y = 6. Add corresponding sides with the bottom equation, to get 13x = 13, or x = 1. Now, 6*1 - y = 3, or -y = 3-6 = -3, or y = 3. \n" ); document.write( " \n" ); document.write( " |
