You can put this solution on YOUR website!
6x + 7y = -8
\n" ); document.write( "-6x- 14y = 22
\n" ); document.write( "--------------adding eliminates x, find y
\n" ); document.write( "-7y = 14
\n" ); document.write( "y = $\"14%2F%28-7%29\"$
\n" ); document.write( "y = -2
\n" ); document.write( ":
\n" ); document.write( "Find x using the 1st equation
\n" ); document.write( "6x + 7(-2) = -8
\n" ); document.write( "6x - 14 = -8
\n" ); document.write( "6x = -8 + 14
\n" ); document.write( "6x = 6
\n" ); document.write( "x = 1
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the 2nd equation
\n" ); document.write( "-6(1) - 14(-2) = 22
\n" ); document.write( "-6 + 28 = 22 \n" ); document.write( "

\n" );
