Algebra.Com's Answer #157782 by Theo(13342)![]() ![]() You can put this solution on YOUR website! 4x+y= -3 \n" ); document.write( "4x+2y=2 \n" ); document.write( "----- \n" ); document.write( "y = 5 \n" ); document.write( "x = -2 \n" ); document.write( "are the answer i think we are looking for. \n" ); document.write( "we'll confirm graphically. \n" ); document.write( "that point (-2,5) should be the intersection of the two lines formed by these equations. \n" ); document.write( "----- \n" ); document.write( "to graph these equations, we need to translate into graphing form. \n" ); document.write( "that's where the y is on the left side of the equal sign and the rest is on the right. \n" ); document.write( "----- \n" ); document.write( "4x + y = -3 becomes y = -3 - 4x which is the xame as y = -4x - 3 \n" ); document.write( "4x + 2y = 2 becomes 2y = -4x - 2 which becomes y = -2x + 1 after dividing both sides of the equation by 2. \n" ); document.write( "our equations in graphing form are: \n" ); document.write( "y = -4x - 3 \n" ); document.write( "y = -2x + 1 \n" ); document.write( "----- \n" ); document.write( "graph of these equations looks like: \n" ); document.write( "----- \n" ); document.write( " \n" ); document.write( "----- \n" ); document.write( "the graph confirms the answer for the simultaneous equations is x = -2 and y = 5 because that is the intersection of the lines formed by the 2 equations. \n" ); document.write( "----- \n" ); document.write( " |
