Algebra.Com's Answer #584152 by Zucchini(70)![]() ![]() ![]() You can put this solution on YOUR website! Solve for y in the second equation: \n" ); document.write( "Y = -2x + 5\r \n" ); document.write( "\n" ); document.write( "Now plug y into the first equation and solve:\r \n" ); document.write( "\n" ); document.write( "3x + 2(-2x + 5) = 8 \n" ); document.write( "3x -4x + 10 = 8 \n" ); document.write( "-x = -2 \n" ); document.write( "X = 2\r \n" ); document.write( "\n" ); document.write( "Now plug x into the second equation and solve (you can use the one where we solved for y) :\r \n" ); document.write( "\n" ); document.write( "Y = -2(2) + 5 \n" ); document.write( "Y = -4 + 5 \n" ); document.write( "Y = 1\r \n" ); document.write( "\n" ); document.write( "The answer is (2,1) \n" ); document.write( " |
