Question 1130673
Use substitution to solve the system. (Simplify your answer completely. If there is no solution, enter NO SOLUTION.)

3y = −12x + 8
4x + y = 3
<pre>3y = - 12x + 8 ------ eq (i)
4x + y = 3_______y = 3 - 4x ------ eq (ii)
From eq (ii), SIMPLY substitute 3 - 4x in eq (i) for y to get:
3(3 - 4x) = - 12x + 8
9 - 12x = - 12x + 8
- 12x + 12x = 8 - 9
From above, we see that: {{{highlight_green(0 <> - 1)}}}.
Therefore, the system has NO SOLUTIONS, and both graphs will be PARALLEL, as they have the same SLOPE.
That's it! NOTHING more, NOTHING less!
