Solving for Two Variables using Elimination
\n" ); document.write( " 8x + 6y = 4
\n" ); document.write( "-8x + 5y = 62
\n" ); document.write( "----------------addition eliminates x, find y
\n" ); document.write( "0 + 11y = 66
\n" ); document.write( "y = 66/11
\n" ); document.write( "y = 6
\n" ); document.write( ":
\n" ); document.write( "find x using the 1st equation, replace y with 6
\n" ); document.write( "8x + 6(6) = 4
\n" ); document.write( "8x + 36 = 4
\n" ); document.write( "8x = 4 - 36
\n" ); document.write( "x = -32/8
\n" ); document.write( "x = -4
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check in the 2nd equation
\n" ); document.write( "-8(-4) + 5(6) = 62
\n" ); document.write( "+32 + 30 = 62
\n" ); document.write( " \n" ); document.write( "
\n" );
