Algebra.Com's Answer #483427 by Alan3354(69443)![]() ![]() You can put this solution on YOUR website! i am starting substitution but i don't know to do this problem or is it elimination?\r \n" ); document.write( "\n" ); document.write( "4y-x=-24 \n" ); document.write( "3x=12y+72 \n" ); document.write( "=============== \n" ); document.write( "The problem is not substitution or elimination. \n" ); document.write( "Those are 2 methods you can use to solve any of this type of problem. \n" ); document.write( "----------- \n" ); document.write( "4y-x=-24 --> x = 4y + 24 \n" ); document.write( "3x=12y+72 /3 --> x = 4y + 24 \n" ); document.write( "---- \n" ); document.write( "It's the same eqn twice. \n" ); document.write( "Dependent, no unique solution. \n" ); document.write( "Infinite # of solutions. \n" ); document.write( " \n" ); document.write( " |
