\n" ); document.write( "...
\n" ); document.write( "Multiply the first equation by 3 and subtract the two equations
\n" ); document.write( "3(x-y = -4) to get 3x - 3y = -12
\n" ); document.write( "subtracting to get
\n" ); document.write( "3x - 3x - 3y - -6y = -12 - -6
\n" ); document.write( "3y = -6
\n" ); document.write( "\"highlight_green%28y=-2%29\"
\n" ); document.write( "...
\n" ); document.write( "Substitute y into the first equation and solve for x
\n" ); document.write( "x - -2 = -4
\n" ); document.write( "x + 2 = -4
\n" ); document.write( "x = -4 - 2
