Algebra.Com's Answer #143694 by Mathtut(3670)![]() ![]() ![]() You can put this solution on YOUR website! y = -3x + 19.........eq 1 \n" ); document.write( "y = 2x -1............eq 2 \n" ); document.write( ": \n" ); document.write( "take the value of y from eq 2 and plug it into eq 1 \n" ); document.write( ": \n" ); document.write( "2x-1=-3x+19 \n" ); document.write( ": \n" ); document.write( "5x=20 \n" ); document.write( ": \n" ); document.write( "x=4 \n" ); document.write( ": \n" ); document.write( "now take x's found value and plug it into either equationa and solve for y. I will use eq 2 \n" ); document.write( ": \n" ); document.write( "y=2(4)-1=7 \n" ); document.write( ": \n" ); document.write( "(4,7) is the solution meaning this is a consistent and independent system since the is one a only one solution \n" ); document.write( " \n" ); document.write( " |
