Algebra.Com's Answer #28971 by venugopalramana(3286)![]() ![]() You can put this solution on YOUR website! Write the augmented matrix for each system of equations \n" ); document.write( " x + 3y = 5.................EQN.I \n" ); document.write( " y - 4z = 8.................EQN.II \n" ); document.write( " -2x + 5z = 7.................EQN.III...I CORRECTED IT AS +5Z..YOU TYPED =5Z \n" ); document.write( "TO WRITE AUGMENTED MATRIX \n" ); document.write( "1.WRITE THE EQNS.SYSTEMATICALLY PUTTING X,Y,Z ETC.(UNKNOWNS/VARIABLES) TERMS IN ORDER ON THE L.H.S.FOLLOWED BY = AND THEN THE CONSTANTS ON THE R.H.S.FOR EACH EQUATION.TILL YOU GAIN EXPERIENCE PUT ZERO*X..OR...0*Y...OR...0*Z ETC,IF X/Y/Z ARE ABSENT \n" ); document.write( "2.NOW PUT coefficients of x,y,z etc in different columns and add last column with constants...FROM ONE EQN. IN EACH ROW. \n" ); document.write( "3.WE GET AS MANY ROWS AS THERE ARE EQNS. AND AS MANY COPLUMNS AS THERE ARE UNKNOWNS PLUS ONE ADDITIONAL COLUMN FOR CONSTANTS.HERE WE HAVE 3 EQNS. AND 3 UNKNOWNS.HENCE WE GET 3 ROWS AND 3+1=4 COLUMNS. \n" ); document.write( "THE AUGMENTED MATRIX IS \n" ); document.write( "|1,3,0,5| \n" ); document.write( "|0,1,-4,8| \n" ); document.write( "|-2,0,5,7| \n" ); document.write( " |
