Which is a solution for the following system of equations?
\n" ); document.write( "y = x^2
\n" ); document.write( "y=-4x + 12
\n" ); document.write( "----------------------
\n" ); document.write( "Substitute and solve for \"x\":
\n" ); document.write( "x^2= -4x+12
\n" ); document.write( "---
\n" ); document.write( "x^2+4x-12 = 0
\n" ); document.write( "x^2+6x-2x-12 = 0
\n" ); document.write( "x(x+6)-2(x+6) = 0
\n" ); document.write( "(x+6)(x-2) = 0
\n" ); document.write( "x = -6 or x = 2
\n" ); document.write( "------------------------------------
\n" ); document.write( "If x = -6, y = 36
\n" ); document.write( "-----
\n" ); document.write( "If x = 2, y = 4
\n" ); document.write( "======================
