solve this equation :x^2-2x+2=y and 4x-7=y to find x and y
\n" ); document.write( ":
\n" ); document.write( "Since they both = y, you can write it:
\n" ); document.write( "x^2 - 2x + 2 = 4x - 7
\n" ); document.write( ":
\n" ); document.write( "x^2 - 2x - 4x + 2 + 7 = 0
\n" ); document.write( "x^2 - 6x + 9 = 0
\n" ); document.write( ":
\n" ); document.write( "Factor this to:
\n" ); document.write( "(x-3)(x-3) = 0
\n" ); document.write( "x = + 3
\n" ); document.write( ":
\n" ); document.write( "Substitute 3 for x to find y:
\n" ); document.write( "y = 3^2 - 2(3) + 2
\n" ); document.write( "y = 9 - 6 + 2
\n" ); document.write( "y = 5
\n" ); document.write( ":
\n" ); document.write( "Do the same in y = 4x - 7
\n" ); document.write( "y = 4(3) - 7
\n" ); document.write( "y = 12 - 7
\n" ); document.write( "y = 5 also \n" ); document.write( "
\n" );
