Algebra.Com's Answer #352275 by april4869(19)![]() ![]() You can put this solution on YOUR website! Solving for these variables is simply eliminating and dividing. For example... \n" ); document.write( "The first equation, you need to solve for x and y, since z is not in the first equation. \n" ); document.write( "x+10y=7 \n" ); document.write( "x=(7-10y) \n" ); document.write( "And y: \n" ); document.write( "10y=7-x \n" ); document.write( "y=(7-x)/10 \n" ); document.write( "Now in this equation we need to solve for x and z, since y is not in this equation. \n" ); document.write( "x+2z=4 \n" ); document.write( "x=(4-2z) \n" ); document.write( "And z: \n" ); document.write( "2z=4-x \n" ); document.write( "z=(4-x)/2\r \n" ); document.write( "\n" ); document.write( "Hope this helps:) \n" ); document.write( " |
