You can put this solution on YOUR website!
3a+b = 1
\n" ); document.write( "2a+3b = 8
\n" ); document.write( "I'm not sure what you want to do here, you need to specify what it is that you need.
\n" ); document.write( "I'll solve by elimination and hopefully it helps you.
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "3a+b = 1 multiply both sides times -3 and add to the next equation:
\n" ); document.write( "-9a+(-3b) = -3
\n" ); document.write( "+
\n" ); document.write( "2a+3b = 8
\n" ); document.write( "---------------------
\n" ); document.write( "-7a 0b = 5
\n" ); document.write( "-7a = 5
\n" ); document.write( "a = -5/7
\n" ); document.write( "Now find b by substituting a with -5/7
\n" ); document.write( "3(-5/7)+b = 1
\n" ); document.write( "-15/7 + b = 1
\n" ); document.write( "Rewrite like this:
\n" ); document.write( "b + -15/7 = 1
\n" ); document.write( "b = 1 + 15/7
\n" ); document.write( "b = 22/7
\n" ); document.write( "~~~~~~~~~~~~~~~~~~~~
\n" ); document.write( "Check:
\n" ); document.write( "3(-5/7) + (22/7) = 1
\n" ); document.write( "-15/7 + 22/7 = 7/7 = 1 Well, this one’s correct
\n" ); document.write( "2(-5/7) + 3(22/7) = 8
\n" ); document.write( "-10/7 + 66/7 = 56/7 = 8 How do you know, this one’s also correct ;-)\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
