Answer:
C. (-4, -3)
Step-by-step explanation:
The point where the lines cross is the solution to both equations. That point is in the third quadrant, where both coordinate values are negative.
The x-coordinate of the point is listed first, so the solution is ...
(x, y) = (-4, -3)
First divide both sides by 12 so u get 5x -4.5 = 3. Now add 4.5 to both sides and u get 5x = 7.5. Now divide 7.5 by 5 and u get 1.5
