Algebra.Com's Answer #232140 by Fombitz(32388)![]() ![]() You can put this solution on YOUR website! Look for combinations of the equations that allow you to eliminate a variable. \n" ); document.write( "If you multiply eq. 1 by (-2) and add it to eq. 2 you will eliminate x. \n" ); document.write( "Unfortunately in this case you will also eliminate y. \n" ); document.write( "The two equations are depedent, that is, they are the same equation. \n" ); document.write( "If you multiply equation 1 by 2, you will get equation 2. \n" ); document.write( "In this case, every solution of eq. 1 will be a solution of eq. 2 so there are an infinite number of solutions. \n" ); document.write( " \n" ); document.write( " \n" ); document.write( "Which is the typical result you achieve when you have dependent equations. \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( ". \n" ); document.write( "If you get a result similar to \n" ); document.write( " \n" ); document.write( "then you have two parallel lines, an inconsistent system, and will have no solution. \n" ); document.write( " \n" ); document.write( " |
