You can put this solution on YOUR website!
3x - 2t = 4 (1)
\n" ); document.write( "--------------
\n" ); document.write( "2x - 5 = -t on this equation add t and 5 on both sides and you get:
\n" ); document.write( "2x + t = 5 now multiply all times 2:
\n" ); document.write( "4x + 2t = 10 add this equation to (1):
\n" ); document.write( "-------------------------------------------------
\n" ); document.write( "3x - 2t = 4
\n" ); document.write( "+
\n" ); document.write( "4x + 2t = 10
\n" ); document.write( "--------------
\n" ); document.write( "7x 0t = 14
\n" ); document.write( "7x = 14
\n" ); document.write( "x = 14/7 = 2
\n" ); document.write( "now that you know x = 2, solve for t:
\n" ); document.write( "3x - 2t = 4
\n" ); document.write( "3(2) - 2t = 4
\n" ); document.write( "6 - 2t = 4
\n" ); document.write( "-2t = -2
\n" ); document.write( "t = -2/-2 = 1
\n" ); document.write( "-------------------
\n" ); document.write( "Check, to check use the other equation:
\n" ); document.write( "2x - 5 = -t
\n" ); document.write( "2(2) - 5 = -1
\n" ); document.write( "4 - 5 = -1 Correct\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
