4x+3y=12

Answer:

B, C, F

Step-by-step explanation:

Given:

$\left\{\begin{array}{l}4x+3y=12\\ \\2x+3y=-6\end{array}\right.$

Subtract the second equation from the first equation:

$(4x+3y)-(2x+3y)=12-(-6)\\ \\4x+3y-2x-3y=12+6\\ \\2x=18\\ \\x=9$

Option B "The x coordinate of the solution is 9" is ture

Substitute it into the first equation:

$4\cdot 9+3y=12\\ \\36+3y=12\\ \\3y=12-36\\ \\3y=-24\\ \\y=-8$

Option F "The y coordinate of the solution is -8" is true.

Point (9,-8) is in the IV quadrant, so option C is true.
