Use substitution to solve the system. (Simplify your answer completely. If there is no solution, enter NO SOLUTION.)\r
\n" ); document.write( "\n" ); document.write( "3y = −12x + 8
\n" ); document.write( "4x + y = 3
\n" ); document.write( "

3y = - 12x + 8 ------ eq (i)
\n" );
document.write( "4x + y = 3_______y = 3 - 4x ------ eq (ii)
\n" );
document.write( "From eq (ii), SIMPLY substitute 3 - 4x in eq (i) for y to get:
\n" );
document.write( "3(3 - 4x) = - 12x + 8
\n" );
document.write( "9 - 12x = - 12x + 8
\n" );
document.write( "- 12x + 12x = 8 - 9
\n" );
document.write( "From above, we see that: .
\n" );
document.write( "Therefore, the system has NO SOLUTIONS, and both graphs will be PARALLEL, as they have the same SLOPE.
\n" );
document.write( "That's it! NOTHING more, NOTHING less! \n" );
document.write( "

\n" );
