Algebra.Com's Answer #178418 by oberobic(2304)![]() ![]() ![]() You can put this solution on YOUR website! First, get both equations into y = mx + b format. \n" ); document.write( ". \n" ); document.write( "3x -y = 24 \n" ); document.write( "Add y to both sides \n" ); document.write( "3x = 24 + y = y + 24 \n" ); document.write( "Subtract 24 from both sides \n" ); document.write( "3x - 24 = y \n" ); document.write( "y = 3x - 24 \n" ); document.write( ". \n" ); document.write( "3x + 4y = -6 \n" ); document.write( "Subtract 3x from both sides \n" ); document.write( "4y = -6 - 3x = -3x - 6 \n" ); document.write( "Divide by 4 \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "Graph: \n" ); document.write( ". \n" ); document.write( " \n" ); document.write( ". \n" ); document.write( "The lines intersect, so we know the system of equations have a solution, so they're consistent.
