↣ Substitute all domains in the equation for the ranges.
[tex]12x+6y=24[/tex]
[tex]2x+y=4[/tex] ↣ Divide the whole equation by 6.
↣ Substitute x = -4 in the equation.
[tex]2(-4)+y=4\\-8+y=4\\y=4+8\\y=12[/tex]
Our range is 12 when x = -4. In the choice there is only one choice that has range value as 12. Therefore, the answer is B.
↣ If you want me to solve for all ranges then you can reply under this. Since there is only one choice that has 12 as range value, I decide not to continue. So If you want me to solve for all ranges then feel free to reply under this. ↣
