Algebra.Com's Answer #451028 by htmentor(1343)![]() ![]() You can put this solution on YOUR website! These two equations are not independent--the 2nd equation is obtained by multiplying the 1st by 2 \n" ); document.write( "There are infinitely many solutions, since we have one equation and two unknowns. \n" ); document.write( "For example, if x=0 -> y=-5 ; if x=2 -> y=-2, etc. \n" ); document.write( " |
