Algebra.Com's Answer #544044 by josgarithmetic(39618)![]() ![]() ![]() You can put this solution on YOUR website! Which way do you want to solve the system? A good but less advanced way is substitute for z in the other two equations and you will have a system of two equations in two linear variables x and y.\r \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( " \n" ); document.write( " \n" ); document.write( "\n" ); document.write( "Continue solving with that simpler system however you want. \n" ); document.write( " |
