solve this equation using the elimination method:
\n" ); document.write( "x + 6y = 79
\n" ); document.write( "x - 4y =-41
\n" ); document.write( "------------Subtraction eliminates x, find y
\n" ); document.write( "10y = 120
\n" ); document.write( "y = 120/10
\n" ); document.write( "y = 12
\n" ); document.write( ":
\n" ); document.write( "Find x using the 1st equation
\n" ); document.write( "x + 6(12) = 79
\n" ); document.write( "x + 72 = 79
\n" ); document.write( "x = 79 - 72
\n" ); document.write( "x = 7
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions of x=7, y=12 in 2nd equation
\n" ); document.write( "7 - 4(12) = -41
\n" ); document.write( "7 - 48 = -41
\n" ); document.write( " \n" ); document.write( "
\n" );
