document.write( "Question 129409: Can you help me with a substitution problem? I am still getting confused,usually with the second part of the problem.It's not in a book.I do not think there is a solution for both of them to make them come out correctly.I really need simple step by step help in order to learn how to do them on my own.Can I just plug each of the sets of numbers given? Your help is greatly appreciated. .The problem is:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( " x=2y-8 3x-2y= -12 \r

You can put this solution on YOUR website!
X=2Y-8
\n" ); document.write( "3X-2Y=-12
\n" ); document.write( "3(2Y-8)-2Y=-12
\n" ); document.write( "6Y-24-2Y=-12
\n" ); document.write( "4Y=-12+24
\n" ); document.write( "4Y=12
\n" ); document.write( "Y=12/4
\n" ); document.write( "Y=3 ANSWER.
\n" ); document.write( "X=2*3-8
\n" ); document.write( "X=6-8
\n" ); document.write( "X=-2 ANSWER.
\n" ); document.write( "PROOF:
\n" ); document.write( "3*-2-2*3=-12
\n" ); document.write( "-6-6=-12
\n" ); document.write( "-12=-12
\n" ); document.write( "
\n" );
