You can put this solution on YOUR website!
3x - 5y = 21
\n" ); document.write( "2x + 10y= -26
\n" ); document.write( ":
\n" ); document.write( "Simplify the 2nd equation divide by 2 and you have
\n" ); document.write( "3x - 5y = 21
\n" ); document.write( "x + 5y = -13
\n" ); document.write( "------------------Addition eliminates y, find x
\n" ); document.write( "4x = 8
\n" ); document.write( "x = 8/4
\n" ); document.write( "x = 2
\n" ); document.write( ":
\n" ); document.write( "Find y using the 2nd original equation; replace x with 2
\n" ); document.write( "2(2) + 10y = -26
\n" ); document.write( "4 + 10y = -26
\n" ); document.write( "10y = - 26 - 4
\n" ); document.write( "10y = -30
\n" ); document.write( "y = -30/10
\n" ); document.write( "y = -3
\n" ); document.write( ":
\n" ); document.write( ":
\n" ); document.write( "Check solutions in the 1st equation, replace x with 2; and y with -3
\n" ); document.write( "3(2) - 5(-3) = 21
\n" ); document.write( "6 - (-15) = 21
\n" ); document.write( "minus a minus is a plus
\n" ); document.write( "6 + 15 = 21; checks our solutions
\n" ); document.write( " \n" ); document.write( "
\n" );
