Algebra.Com's Answer #292562 by algebrahouse.com(1659)![]() ![]() You can put this solution on YOUR website! -30x - 15y = -30 \n" ); document.write( "30x + 15y = 30 \n" ); document.write( "--------------- \n" ); document.write( "0 = 0 \n" ); document.write( "= infinite solutions\r \n" ); document.write( "\n" ); document.write( " \n" ); document.write( "When the variable disappears and you get a true statement, such as 0 = 0, \n" ); document.write( "then there are \"infinite solutions\". This means, the two lines intersect \n" ); document.write( "in an infinite number of points. In other words, the two equations are equivalent, \n" ); document.write( "and would create the same line when graphed.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "When the variable disappears and you get a false statement, such as 0 = 3, \n" ); document.write( "then thee is \"no solution\". This means, the two lines would not intersect. \n" ); document.write( "In other words, the two equations, when graphed, would create parallel lines. \n" ); document.write( "www.algebrahouse.com \n" ); document.write( " \n" ); document.write( " |
