Algebra.Com's Answer #266839 by robertb(5830)![]() ![]() You can put this solution on YOUR website! 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( " |
