Answer:
The answer is C
Step-by-step explanation:
12+8=20
Then you subtract 20 by 5
you would take 264+77+150=491in2
Eliminate
multiply first equatin by -2
mulitply second by 3 and add them
-6x-14y=8
6x+15y=-6
add them
y=2
sub
3x+7(2)=-4
3x+14=-4
minus 14
3x=-18
divide 3
x=-6
(-6,2)
Assuming a direct proportional variation.
