Algebra.Com's Answer #66997 by tanimachatterjee(60)![]() ![]() ![]() You can put this solution on YOUR website! here we have 2 equations x+y=12 ...........(1) \n" ); document.write( " and y=2x ..........(2) \n" ); document.write( " now we can replace the value of y of equation (1) by 2x \n" ); document.write( "so we have x+2x =12 \n" ); document.write( "or 3x =12 \n" ); document.write( "or x = 12/3= 4\r \n" ); document.write( "\n" ); document.write( "we know from equation (2) that y = 2x \n" ); document.write( "therefore value of y = 2*4= 8\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " ans ..... x = 4 and y = 8 \n" ); document.write( " |
