Not sure what you mean by TI Nspire.
\n" ); document.write( "You can use elimination here.
\n" ); document.write( "Multiply the first equation by 3.
\n" ); document.write( "3(2a - b = 1)
\n" ); document.write( "Your system is now:
\n" ); document.write( "6a - 3b = 3
\n" ); document.write( "5a - 3b = 0
\n" ); document.write( "Look at your coefficients. Are there any opposite signs or same signs?
\n" ); document.write( "YES! The \"b\"s have the same coefficients.
\n" ); document.write( "This means to ADD the equations.
\n" ); document.write( "The \"b\"s cancel out now.
\n" ); document.write( "11a = 3
\n" ); document.write( "Divide by 11 on both sides
\n" ); document.write( "a = 3/11\r
\n" ); document.write( "\n" ); document.write( "Plug in 3/11 for \"a\" in either equation and solve for \"b\"
\n" ); document.write( "5(3/11) - 3b = 0
\n" ); document.write( "15/11 - 3b = 0
\n" ); document.write( "Subtract 15/11 on both sides
\n" ); document.write( "-3b = -15/11
\n" ); document.write( "Divide by -3 on both sides.
\n" ); document.write( "b = 15/33\r
\n" ); document.write( "\n" ); document.write( " \n" ); document.write( "
\n" );
