we are given two equations in two unknowns,
\n" ); document.write( "x + y = 3
\n" ); document.write( "x - y = 11
\n" ); document.write( "add the two equations
\n" ); document.write( "2x = 14
\n" ); document.write( "x = 7, y = -4
\n" ); document.write( "********************
\n" ); document.write( "check answer by substituting for x and y in second equation
\n" ); document.write( "7 - (-4) = 11
\n" ); document.write( "7 + 4 = 11
\n" ); document.write( "11 = 11
\n" ); document.write( "our answer checks\r
